ΔABC is isosceles with AB = AC. Also. AD ⊥ BC meeting BC in D. Are the two triangles ABD and ACD congruent?
ΔABC is isosceles with AB = AC. Line segment AD bisects ∠A and meets the base BC in D.
In ∆ABC, ∠B = 60°, ∠C = 40°, AL ⊥ BC and AD bisects ∠A such that L and D lie on side BC. Find ∠LAD
Let ΔABC be a triangle such that ∠B = 70° and∠C = 40° . suppose D is a point on BC such that AB = AD. Prove that AB > CD.
In a triangle ABC, AB = AC. Points G on AB and D on AC are such that AE = AD.
