Geometry3.11 Trapezoid

Trapezoid/Trapezium \ ĐA + Đ D = 180° and Đ B + Đ C = 180°.

Example:

Solution:
Since AB is parallel to CD, we have
Đ A + Đ D = 180° and Đ B + Đ C = 180°.
So Đ D = 180° - Đ A = 180° - 50°
Đ D = 130°
Đ B + Đ C = 180°
Đ C = 180° - Đ B
Đ C = 180° - 70°
Đ C = 110°

Directions:
• Draw a trapezoid and explain the different properties of a trapezium, in your own words, with examples.
