## Are opposite sides always parallel?

Opposite sides are parallel. All angles are congruent. Only one pair of opposite sides is parallel.

## What are not parallel sides?

Explanation: The American term for such a quadrilateral is a trapezium, and the British term is a trapezoid. It is a quadrilateral that has no parallel sides.

What shape does not have a parallel side?

Triangles are shapes that have no parallel sides. All triangles will have three sides and it is impossible for any of them to be parallel. If two lines out of three were parallel, it would be impossible to draw the shape.

Does a rhombus have 4 right angles?

A rhombus is defined as a parallelogram with four equal sides. Is a rhombus always a rectangle? No, because a rhombus does not have to have 4 right angles. Kites have two pairs of adjacent sides that are equal.

### Do triangles have 3 equal sides?

An equilateral triangle has three equal sides and angles. It will always have angles of 60° in each corner.

### 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. A kite is a quadrilateral with exactly two pairs of adjacent congruent sides. (This definition excludes rhombi.

Can a rhombus have 2 90 degree angles?

Explanation: As a parallelogram, rhombus has a sum of two interior angles that share a side equal to 180∘ . Therefore, only if all angles are equal, they all are equal to 90∘ .

Are all angles of a rhombus 90 degrees?

Besides having four sides of equal length, a rhombus holds diagonals that bisect each other at 90 degrees, i.e., right angles. 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°.

## What do you call a triangle with 2 equal sides?

Isosceles. An isosceles triangle can be drawn in many different ways. It can be drawn to have two equal sides and two equal angles or with two acute angles and one obtuse angle.

## What are the 3 triangles called?

There are three types of triangle based on the length of the sides: equilateral, isosceles, and scalene.
