Rosa represents her school as -2, because it is two blocks south of her house. Yesterday, Rosa left school and walked either north or south to a friend's house. If she walked four blocks, which values could represent where she ended up? Select all that apply.

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

it's both, now can you answer my most recent question?

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
