Which describes the transformation? Select three options.
Katyanochek1 [597]

Answer:

It is rigid

It is isometric

The size is preserved

Step-by-step explanation:

Given that Triangle ABC was translated to form A'B'C', then both triangles are congruent triangles.

A translation only moves the figure, preserving the size.

Because the size is preserved, it is a rigid transformation or isometric transformation.

A triangle has side lengths of 7 in., 9 in., and 11 in. Determine whether this is a right triangle and why.
Harlamova29_29 [7]

Answer:

Not a right triangle.  See below for my reasoning.


Step-by-step explanation:

If this is a right triangle, then the sum of the squares of the two shorter sides will equal the square of the longest side:  7^2 + 9^2 = 11^2 => 49 + 81 = 121   But this is false.
