Which of the following is proper notation to describe the set of all letters in the alphabet? {a, b, c . . . z} (a, b, c, etc.) a through z none of the above

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

83-45=38

38 was the other number

hope your goes well, here's a turkey

-thekoolkid1o1

the correct answer would be d because the slope is -2/2=1 and the y intercept is at 2 so that is the correction equation

tbh idk i hope this heples
