Suppose that m∠A = m∠D. Which other fact would guarantee that the triangles are SIMILAR? A) AB DE = CB FE B) m∠C = m∠F C) m∠A + m∠B + m∠C = 180° D) 180° - m∠D = m∠E + m∠F
Figures are called similar when they have the same shape. If the size is also the same, they are called congruent. Two triangles have to be similar or congruent if their angles are the same.
Have fun mathing!
