Question

1. a reflection over which line will carry the isosceles triangle onto itself? * 1 point

x - axis
y - axis
x = -1
y = x

Explanation:

Step1: Recall reflection property

A reflection that maps a figure onto itself is over its line of symmetry.

Step2: Analyze isosceles - triangle

An isosceles triangle has a line of symmetry that divides it into two congruent halves. For the given isosceles triangle on the coordinate - plane, the y - axis divides it into two mirror - image halves.

Answer:

B. y - axis
