Question

Chords DE, EF, and FG are congruent. Determine the following measures. m = ° m∠ECF = °

Answer 1

arc FG = 67
angle ECF = 67

This is true because the chord lengths are equal

Answer 2

Given :  Chords DE, EF, and FG are congruent.

To find :  m∠ECF =

Solution:

Chord  DE , EF & FG are congruent.

=> DE = EF = FG

Equal chord subtend equal angle at center

=> ∠FCG = ∠DCE = ∠ECF

m ∠DCE = 67° given

=> m ∠ECF = 67°

m ∠ECF = 67°
