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 ∠ade is 47°. the proof, with a missing reason, proves that the measure of ∠ecb is 43°.
the table info is below.
statement reason
m∠ade = 47° =given
m∠dae = 90° =definition of a right angle
m∠aed = 43° =?
segment de joins the midpoints of segment ab and segment ac =given
segment de is parallel to segment bc =midsegment of a triangle theorem
∠ecb ≅ ∠aed =corresponding angles are congruent
m∠ecb = 43° =substitution property
which theorem can be used to fill in the missing reason?
concurrency of medians theorem
isosceles triangle theorem
triangle inequality theorem
triangle sum theorem
