Question

n Triangle ABC, the length of ¯¯¯¯¯¯¯¯AB is 3 cm, and the length of ¯¯¯¯¯¯¯¯BC is 7 cm. Triangle ABC will be dilated with the center at the origin to create Triangle A′B′C′. If the image of Point A(−3,5) after the dilation is A′(−12,20), what is the length of ¯¯¯¯¯¯¯¯B′C′?

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°).
