Answer:
2.5
Step-by-step explanation:
A triangle ABC with vertices A(0, 0), B(0, 4), and C(6, 0) is dilated to form a triangle A'B'C' with vertices A′(0, 0), B′(0, 10), and C′(15, 0). If the center of dilation is point A or A' (the origin), then
Since
- AB=4;
- A'B'=10;
- AC=6;
- A'C'=15,
then the scale factor of the dilation is
Answer:
[1] Addition property of equality
[2] Division property of equality
Step-by-step explanation:
Given the equation, , the following are steps and justification for each step taken:
=> Given equation
Add 6 to both sides
=> addition property of equality [1]
=> simplify
Divide both sides by 4
=> Division property of equality [2]
=> simplify
The justification for the steps taken are:
[1] Addition property of equality
[2] Division property of equality
Answer:
Measure all sides of the triangle (all 3 sides), and depending on the lengths see if they are all equal, if two are equal, or if there are no equal sides at all. If there are all equal side lengths you have an equilateral triangle that has 3 congruent, aka equal sides.
