A triangle has base b and height h. The base is doubled. Complete the description of how the height
must change so that the area remains the same. Complete the explanation of the reasoning.
The area of the original triangle is -6,h1. The area of the new triangle is
(2b )h 2
This must equal the original area, -b,h1. Therefore, the height must be
(select)

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°).
