Question

Trapezoid A'B'C'D' is the image of trapezoid ABCD under a rigid transformation.

1. Label all vertices on trapezoid A'B'C'D'
2. On both figures, label all known side lengths and angle measures. (for
descriptions, use bottom left corner, top right corner, top left corner.)

Answer 1

Explanation:

a). Trapezoid ABCD has one acute angle, one obtuse angle and two right angles.

Since, angle B is an acute angle, mark the vertex A' having acute angle.

Similarly, Obtuse angle A' for A and other vertices.

b). Rigid transformation doesn't change the size and shape of the image.

Therefore, all angles and measure of sides of ABCD will remain unchanged.

Measure of angle A' = 130°, m∠B' = 50°

m(A'D') = m(AD) = 6 units

m(C'D') = m(CD) = 4 units
