Answer 14

A centroid is the connector of all midpoints in a triangle and it makes 2:1 ratios on each of its lines

Question 15

How to construct an altitude

Answer 15

1. Put compass on top point of triangle, draw curve through bottom line, hitting line twice
2. Put compass on intersection points without changing distance and draw a small curve on each intersection points without
