Question

In the diagram of ABCD shown below, 'BA is drawn from vertex B to point A on DC, such that BC & BA.Аa.b.What kind of triangle is AABD? Explain.hat kind of triangle is ADBC? Explain.

Answer 1

We have the following information from the picture:

mmWe have that:

m m m

m m

Therefore, the angles in triangle ABD are m < D = 30, m< DAB = 120, and m < B = 30.

We need now to find the angles of the triangle ABC to find the rest of the angles.

In triangle ABC, we need to find the

Then, we can draw this as follows:

According to the angles, the triangle ABC is an Obtuse Triangle because it has an obtuse angle (

The triangle DBC is a right triangle because it has a right angle (
