Question

In triangle ABC median AM bisects the Base BC prove that triangle ABC is isosceles.​

Answer 1

Step-by-step explanation:

The triangle ABM is congruent to triangle ACM

As median AM is common

BM is equal to CM

And angle BAM is equal to angle CAM

Answer 2

Step-by-step explanation:

IN Triangle ABM and ACM

AM=AM(common)

BM=CM(Am is a bisector)

angle MAB=angle MAC ( Am is bisector)

By SAS Triangle ABM is Congruent to ACM

therefore AB = AC by cpct
