Which ones are parallel, perpendicular or intersecting

plug them in a graphing calculator and you'll automatically get ur answer! Or use y = mx + b method and b would be your y-int (0,b)! mx is example: 2/1 or 2/4! Top number counts up if the mx is positive, if mx is negative it goes down! The bottom number fraction count how far it goes to the right side! mx is constant so it will keep going forever!

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
