Question

lara has a triangle that has side lengths of 26, 34, and 58. she wants to reduce the triangle by one half, so she divides each side and each angle measurement by 2. what error did lara make? lara should have only divided the angles by 2 in order to reduce the triangle. lara should have multiplied each measurement by $\frac{1}{2}$. lara should have only divided the side lengths by 2 in order to reduce the triangle. lara did not make an error.

Explanation:

When reducing a triangle (creating a similar triangle), the side - lengths are scaled (in this case, divided by 2). But the angles of similar triangles are congruent. So, Lara should not have divided the angles by 2. She should only have divided the side lengths by 2.

Answer:

Lara should have only divided the side lengths by 2 in order to reduce the triangle.
