Aparallelogram has four congruent angles. which name best describes the figure?

kite

rectangle

rhombus

trapezoid

A parallelogram whose four angles are congruent is rectangle  

Step-by-step explanation:

Given that a parallelogram has four congruent angles.

we have to choose the best name which describes the figure.

A parallelogram is a quadrilateral with opposite sides parallel and equal.

As all the four angles are congruent which means all the four angles are equal.

Let the measure of congruent angle is x

By the angle sum property, the sum of all angles of quadrilateral is equal to 360°

⇒ x+x+x+x=360

Hence, the measure of all 4 angles of Parallelogram is equal to 90°

From the given figures the rectangle is the only figure in which the measure of all angles 90°. Opposite sides of rectangle are parallel and equal.

∴ A parallelogram whose four angles are congruent is rectangle

step-by-step explanation:

one triangle is 2.5 times bigger than the other triangle.
