Question

1)

Answer 1

Answer:

1.10

2.90 degrees

3.Medians

Step-by-step explanation:

We are given that

1.Segment GB is  a median of triangle ABC.

AG=10 units

We have to find the measure of segment GC.

We know that median divides the opposite side of triangle into two equal halves.

Therefore, AG=GC=10 units

2.We are given that segment BD is an altitude of triangle ABC.

We know that altitude BD is perpendicular to side AC.

Therefore, $\angle BDC=90^{\circ}$

3.Centroid: It is the intersection point of medians where three medians of triangle meet .

Answer:Medians
