Question: Triangle sum theorem: The sum of the interior angle measures of a triangle is 180˚ Given: ΔABCwith DE↔∥AC¯ Prove: m∠1+m∠2+m∠3=180∘ Proof: 1.

Question: Triangle ABC is a right triangle. Point D is the midpoint of side AB and point E is the midpoint of side AC. The measure of angle ADE is 36°. The proof, with a missing reason, …

The sum of the angle measures of the two non-right angles of a right triangle is 90°. The Weak Exterior Angle Theorem 43 is now an immediate conse- quence of a much stronger theorem.

Prove: x = 20 By the triangle sum theorem, the sum of the angles in a triangle is equal to 180°. Therefore using the given and triangle sum theorem, mZP+mZQ+mZR=180°.
