# Which figure is the odd one out triangle?

## Which figure is the odd one out triangle?

1. Answer: The triangle is the odd one out because it has only 3 line segments. The other figures have 4 line segments.

## Which is the odd one out a square a rectangle or a pentagon?

Of the four, the square is the only polygon which specifically has all sides of the same length. One might rephrase the options to be “a pentagon, a special kind of rectangle, a rectangle, and a triangle,” in which case I’d identify the square (i.e. the “special kind of rectangle”) as being the odd one out.

Which is the odd one out cube square circle?

Square is the odd one out of the rest. Here in case of cube, sphere and cylinder, the objects are 3 dimensional.

Which of the following quadrilateral is odd?

Irregular Quadrilaterals The only regular (all sides equal and all angles equal) quadrilateral is a square. So all other quadrilaterals are irregular.

### Does a rhombus have a 90 angle?

The intersection of the diagonals of a rhombus form 90 degree (right) angles. This means that they are perpendicular. The diagonals of a rhombus bisect each other.

### Does a rhombus have 4 90 degree angles?

1 Answer. If a rhombus is a square, all four of its angles are right. Otherwise, all angles are either acute or obtuse, but not right.

Are all angles of rhombus 90?

On the other hand, as the basic property of square states that all its interior angles are right angles, a rhombus is not considered as square, unless all the interior angles measure 90°. Any rhombus includes four angles, out of which the opposite ones are equal to each other.

Is all angles of rhombus are equal?

The angles of each pair of opposite vertices are equal. A rhombus is a special case of a parallelogram, a quadrilateral with equal and parallel opposite sides. A square is a special case of a rhombus, where all four vertex angles are equal to 90°.

#### What is the longer diagonal of a rhombus?

Given that the longer diagonal of a rhombus is equal to √3 times one of its sides also the length of a side is 6 inches. The half of both the diagonals form a right triangle with a side of the rhombus.

#### Is the diagonal of a rhombus equal?

The diagonals of a rhombus intersect at equal angles, while the diagonals of a rectangle are equal in length.

How do you find a long diagonal?

To find the length of the diagonal, we can consider only the triangle and use the law of cosines to find the length of the unknown side. Where is the length of the unknown side, and are the lengths of the known sides, and is the angle between and .

Does a rectangle only have 90 degree angles?

Opposite sides of a rectangle are the same length (congruent). The angles of a rectangle are all congruent (the same size and measure.) Remember that a 90 degree angle is called a “right angle.” So, a rectangle has four right angles.

## What is the formula for finding the diagonal of a cube?

As discussed earlier, in a cube, all sides have equal length. So, let’s say that each side has a length x. Then, formula to find diagonal of cube = √3x.

## What is the diagonal formula?

You can use the Pythagorean theorem to estimate the diagonal of a rectangle, which can be expressed with the following formula: d² = l² + w² , and now you should know how to find the diagonal of a rectangle explicit formula – just take a square root: d = √(l² + w²) .

What is the diagonal of a triangle?

The diagonal triangle of a complete quadrangle is the triangle formed by its three diagonal points. If the quadrangle is a cyclic quadrilateral, then the circle is the polar circle of the diagonal triangle, i.e., each vertex is the inversion pole of the opposite side with respect to the circle.

What is the diagonal of a right triangle?

To find the length of the diagonal (or hypotenuse) of a right triangle, substitute the lengths of the two perpendicular sides into the formula ​a2​ + ​b2​ = ​c2​, where ​a​ and ​b​ are the lengths of the perpendicular sides and ​c​ is the length of the hypotenuse. Then solve for ​c​.

### Does 4 5 6 make right triangles?

For a set of three numbers to be pythagorean, the square of the largest number should be equal to sum of the squares of other two. Hence 4 , 5 and 6 are not pythagorean triple.

### What is the 30 60 90 Triangle rule?

Tips for Remembering the 30-60-90 Rules Remembering the 30-60-90 triangle rules is a matter of remembering the ratio of 1: √3 : 2, and knowing that the shortest side length is always opposite the shortest angle (30°) and the longest side length is always opposite the largest angle (90°).

Which set of side will make a right triangle?

All that you need are the lengths of the base and the height. In a right triangle, the base and the height are the two sides which form the right angle.

Does 9 12 and 15 make a right triangle?

The three sides 9 in, 12 in, and 15 in do represent a right triangle. Since the square of the hypotenuse is equal to the sum of the squares of the other two sides, this is a right triangle.

hypotenuse

#### Does 5 12 and 13 form a right triangle?

Yes, a right triangle can have side lengths 5, 12, and 13. To determine if sides of length 5, 12, and 13 units can make up the sides of a right…

What is the 5/12/13 Triangle rule?

Essentially, it says that the sine of an angle is proportional to the length of the opposite side in any given triangle. Since we know the lengths of three sides plus one of the angles, we can use this law to solve for the missing angles. For our triangle we now know that a = 5, b = 12, c = 13 and C = 90 degrees.

What type of triangle does 5/12 13?

scalene triangle

## Does 4 8 12 make right triangles?

Answer: No, side lengths of 4, 8, and 12 do not form a right triangle.
