Katee drew a triangle on a coordinate grid. She flipped the triangle over the y-axis from Quadrant I to Quadrant II. Which statement is true? Multiple choice question. Cross out A) The flipped triangle is a translation of the first triangle. Cross out B) The flipped triangle is a reversal of the first triangle. Cross out C) The flipped triangle is a reflection of the first triangle. Cross out D) The flipped triangle is a quadrant of the first triangle.

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19

what is the graph

step-by-step explanation:

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right

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
