a. In order for ΔABC to be similar to ΔDEF, what must be true about the angles? Be specific. b. If you know that ΔABC is similar
igomit [66]
I) if the triangles are similar then the corresponding angles are congruent. this means that the angles are of the same size.

ii)  If ΔABC is similar to ΔDEF, therefore; m∠A = m∠D, m∠B=m∠E, and m∠C=m∠F,
thus, if m∠A= 52, m∠D=52, and if m∠E=65, then m∠B=65, thus to get m∠C; 
180- (52+65)
=  63 , therefore; m∠C= 63

iii) if two figures are similar they have the same shape and not necessarily the same size while if two figures are congruent then they have the same shape and size

zimovet [89]

Answer:

<u>a = 60° or π/3</u>

Step-by-step explanation:

<u>Given :-</u>

sin² a/2 - sin a/2 + 1/4

<u>To find :-</u>

a

<u>Solving :-</u>

sin² a/2 - sin a/2 + 1/4 = (sin a/2 - 1/2)² = 0

sin a/2 - 1/2 = 0

sin a/2 = 1/2

a/2 = 30°

<u>Solution :-</u>

<u>a = 60° or π/3</u>
