Given that the radius of circle a is 4 cm, and the diameter of circle b is 6 cm, what can be concluded about the two circles. sorry that i have no picture i hope this is enough answer choices are below.
a. the circles are similar and congruent
b the circles are congruent only
c. the circles are neither similar nor congruent
d. the circles are similar

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

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
