Question

1. If two triangles ABC and abc are perspective from point P and if sides Aa, Bb, and Cc intersect at point P. what do you call the point of intersection?
(A) Center of perspective (B) axis of perspectivity (C) center of gravity (D) origin

Polygon with three sides, three angles, and three vertices. Based on the properties of each side, the types of triangles are scalene (triangle with three three different lengths and three different angles), isosceles (angle with two equal sides and two equal angles), and equilateral (three equal sides and three angles of 60°). The types of angles are acute (less than 90°); obtuse (greater than 90°); and right (90°).
