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
![\dfrac{A'B'}{AB}=\dfrac{A'C'}{AC}.](https://tex.z-dn.net/?f=%5Cdfrac%7BA%27B%27%7D%7BAB%7D%3D%5Cdfrac%7BA%27C%27%7D%7BAC%7D.)
Since
- AB=4;
- A'B'=10;
- AC=6;
- A'C'=15,
then the scale factor of the dilation is
![k=\dfrac{10}{4}=\dfrac{15}{6}=2.5.](https://tex.z-dn.net/?f=k%3D%5Cdfrac%7B10%7D%7B4%7D%3D%5Cdfrac%7B15%7D%7B6%7D%3D2.5.)
Answer:
cant rlly read the question
Step-by-step explanation:
Step-by-step explanation:
AB = AC ( Given)
angle BAD = angle DAC. (AD bisects BAC)
AD = AD. ( common side )
abd is congruent to adc. ( SAS Axiom)
