Question

The diagram represents a reduction of a triangle by using a scale factor of 0.8.

A larger triangle has a base of 10 inches and height of 6 inches.

What is the height of the reduced triangle?
4.0 inches
4.8 inches
5.2 inches
7.5 inches

Answer 1

After reducing the triangle by a scale factor of 0.8, the new base would be 10 * 0.8 = 8 inches.

Similarly, the new height would be 6 * 0.8 = 4.8 inches.

Therefore, the height of the reduced triangle is 4.8 inches.

So, the answer is: 4.8 inches.
