Answer: Choice A) Triangle ABC is similar to triangle ACD by AA
AA stands for Angle Angle. Specifically it means we need 2 pairs of congruent angles between the two triangles in order to prove the triangles similar. Your book might write "AA similarity" instead of simply "AA".
For triangles ABC and ACD, we have the first pair of angles being A = A (angle A shows up twice each in the first slot). The second pair of congruent angles would be the right angles for triangle ABC and ACD, which are angles C and D respectively.
We can't use AAS because we don't know any information about the sides of the triangle.
Answer:
F,D. C,D
Step-by-step explanation:
This is all I know the F and D make a right angle and the C,D make a 360 degree angle.
The probability of compound events combines at least two simple events, either the union of two simple events or the intersection of two simple events.
Answer: the picture has no answer it's invalid but I will try:
X is a 90 degree angle other than that I can't do anything
Step-by-step explanation:
This is what I got. The standard equation for a hyperbola with a horizontal tranverse axis is - = 1. The center is at (h,k). The distance between the vertices is a 2a. The distance between the foci is 2c. I hope that helped :\
