rhombus

## What quadrilateral has opposite sides equal in length?

Parallelogram

Are opposite sides of a parallelogram always equal in length?

In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

### Does a rectangle have opposite sides that are parallel and the same length?

Rectangle. A rectangle is a quadrilateral with four right angles (90°). It has two pairs of opposite (facing) sides that are equal lengths and parallel.

### What 2 Quadrilaterals have no parallel sides?

In India and Britain, they say trapezium ; in America, trapezium usually means a quadrilateral with no parallel sides.) An isosceles trapezoid is a trapezoid whose non-parallel sides are congruent.

Does a diamond have right angles?

But a diamond also has four equal sides and right angles at the corners. Evidently,the eye-brain combination looks at more than sides and angles. it says something like, “I see a four-sided shape with points on the top and bottom and sticking out of the sides.

## What are examples of right angles?

Examples of right angles are all around us. We can see right angles in the corners of a room, book, cube, windows and at several other places. A vertical and a horizontal line make most common right angles. However, diagonal lines intersecting each other also form right angles.

## Does a diamond have 90 degree angles?

If you have a shape that has 4 equal sides, but only opposite angles are equal, it’s a diamond. The opposite sides are parallel, but the corners do not form right angles. A diamond shape is a good example of a rhombus. The opposite sides are equal, but the corners do not form right angles.

How many right angles does a triangle have?

one right angle

### What is the greatest number of right angles in a triangle?

Explanation: A triangle has 180o as the sum of all its internal angles, no more, no less. If one angle is 90o , then you can have two 45o angles, one 30o and a 60o , an 81o and a 9o – pretty much any combination of numbers adding up to 90 to make the total 90+90=180 .

### Does a triangle have one right angle?

A triangle is composed of three line segments. A triangle that has one right angle is called a right triangle. A triangle that has one obtuse angle is called an obtuse triangle. When a triangle has three congruent sides, we call the triangle an equilateral triangle.

Can a triangle have 3 right angles?

No, real, triangle can have three right angles. The sum of the angles formed must equal 180° and the sum of the length of two sides must be greater than the length of the third.

## Why can a triangle only have one right angle?

Ans- No a triangle cannot have more than one right angle as if there are 2 right angles the their sum will be 180° and the third angle will exceed the sum. Therefore the construction is not possible.

## What are the other 2 angles of a right triangle?

The angles of a triangle add together to 180 degrees. We already know that one of the angles is 90 degrees, so we can subtract 90 from 180: the other 2 angles have to add to 90 degrees.

What is the minimum number of acute angles in a triangle?

two

### How do you find the length of an acute angle?

Divide the length of side “a” by the length of the hypotenuse, side “c.” This is the sine of the acute angle that shares the horizontal leg with the right angle. Enter this ratio into your scientific calculator and use the inverse sine function to determine the angle.

### What is the minimum number of obtuse angles there can be?

Since an obtuse angle is an angle of greater than 90° and less than 180°, 4 obtuse angles would have to sum to greater than 360° at a minimum, which isn’t possible for a quadrilateral.

Can a triangle have 2 right angles?

No, a triangle can never have 2 right angles. A triangle has exactly 3 sides and the sum of interior angles sum up to 180°. Thus, it is not possible to have a triangle with 2 right angles.

## What do the 3 angles of a triangle equal?

The sum of the three angles of any triangle is equal to 180 degrees. Now let’s try a problem.

## Can u have a triangle with 2 obtuse angles?

The answer is “No”. Reason: If a triangle has two obtuse angles, then the sum of all the 3 interior angles will not be equal to 180 degrees.

Can a triangle have all angles less than 60?

No, a triangle cannot have all angles less than 60°, because if all angles will be less than 60°, then their sum will not be equal to 180°.

### Can you have a triangle with all the three angles equal than 60 degree?

Are the angles in an equilateral triangle always 60 degrees? Yes, because a equilateral triangle has 3 equal angles. The 3 angles of a triangle equal 180°. So if the angles are all equal in an equilateral triangle, we do 60 times 3 which equals 180°.

### Can a triangle have all angles?

That is, the statement is true and therefore, yes a triangle can have all angles equal to 60o.

How many triangles can be drawn having its angles 45 64 72?

1 Answer. None, the sum of given angles = 45° + 64° + 72° = 181° ≠ 180°. Hence, we see that sum of all three angles is not equal to 180°. So, no triangle can be drawn with the given angles.

## What is angle sum of a triangle?

Angles in a triangle sum to 180° proof.

## How many triangles can be drawn having angles 45 60 and 85?

Answer: No triangles can be drawn by these angles.

How many triangles can be drawn having its angles 60 90 30?

one triangle
