The scatter plot shows a​ hiker's elevation above sea level during a hike from the base to the top of a mountain. The equation of a trend line for the​ hiker's elevation is y+8.91x+688, where x represents the number of minutes and y represents the​ hiker's elevation in feet. Use the equation of the trend line to estimate the​ hiker's elevation after 160 minutes.

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
