George was weighed at the doctor's office. the scale read 67.20 pounds. the doctor wrote 67.3 pounds on george's chart. did the doctor make a mistake? if he did explain.

Yes, the doctor made a mistake. He should have wrote 67.2 pounds on George's chart. Because when rounded it would be 67.2.

Hope this helps.

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
