Question

for exercise 15, solve the problem. 15. triangle def has coordinates d(2, 3), e(6, 1), and f(2, 0). the triangle is reflected across the x - axis. write the coordinates of △def. (lesson 2)

Explanation:

Step1: Recall reflection rule

When a point $(x,y)$ is reflected across the $x -$axis, the new point is $(x,-y)$.

Step2: Find $D'$

For point $D(2,3)$, applying the rule: $D'=(2,- 3)$.

Step3: Find $E'$

For point $E(6,1)$, applying the rule: $E'=(6,-1)$.

Step4: Find $F'$

For point $F(2,0)$, applying the rule: $F'=(2,0)$.

Answer:

$D'(2,-3), E'(6,-1), F'(2,0)$
