Question

select all the correct answers. in triangle abc, m∠a = 40° and m∠b = 70°. which statements about triangle abc are true? ac > bc ab > ac ac = ab ab > bc ab < bc ac < bc

Explanation:

Step1: 求∠C度数

$180^{\circ}-40^{\circ}-70^{\circ}=70^{\circ}$

Step2: 根据大角对大边判断

∠A = 40°，∠B = ∠C = 70°，所以BC = AC，AB > AC = BC。

Answer:

AB > AC，AB > BC
