Question

Find the measure of the numbered angles

Answer 1

all are 20 degrees
180-140=40
40/2 = 20 angle 1 and 3
if both triangles are similar than 1 2 3 4 are 20 degrees.

Answer 2

Hello!

This is a parallelogram. It is a quadrilateral with two pairs of parallel sides. Here, the opposite angles are alternate, that is, they have togheter 180°.

Rhombus

This is a rhombus. It is a quadrilateral whose four sides all have the same length. Here, the diagonals of a rhombus intersect at equal angles.

A rhombus has opposite angles equal and the figure formed by joining the midpoints of the sides of a rhombus is a rectangle, and vice versa. It has an inscribed circle.

Good luck:)
