Question

use the image to answer the question
a ramp at a skate park is shaped like a triangular prism. from a side view, the ramp appears to be a scalene right triangle
how many lines of symmetry can be found on this triangle?
(1 point)
zero
one
two
three

Explanation:

Step1: Recall line of symmetry definition

A line of symmetry is a line that divides a figure into two congruent mirror - image halves.

Step2: Analyze scalene right triangle properties

A scalene triangle has all sides of different lengths. A right triangle has one right angle. For a right triangle to have a line of symmetry, it would have to be isosceles (since an isosceles right triangle has a line of symmetry along the altitude to the hypotenuse). But a scalene right triangle has no two sides equal, so there is no line that can divide it into two congruent mirror - image halves.

Answer:

zero
