To calculate: Measure of ∠HDC

Expert Solution & Answer

Answer to Problem 21CUR

∠HDC=60°

Explanation of Solution

Given information: AB↔⊥GH↔ , AB↔∥CD↔ and ∠AHD=60°

Calculation:

McDougal Littell Jurgensen Geometry: Student Edition Geometry, Chapter 3, Problem 21CUR

As AB↔∥CD↔ , AB↔∥CE↔

(as CE↔ is the extended part of CD↔ )

Take HD↔ as a transversal.

Use the fact that if a transversal intersects two parallel lines, then alternate interior angles are equal.

So,

∠HDC=∠AHD=60°
