Given point A(−2,3). State the coordinates of the image of A under the composition T(−3,−4) o r(x-axis) .

A'(2,3) -> A"(-5,-7)

500

Solve for x and y

Corresponding angles are equal

Linear angles are supplementary

500

Solve for x and then find the perimeter of the triangle.

x = 2 and 10, 2 is not a solution because it leads to a zero length for a side and a negative length for another side.

So x=10 is the solution which gives a perimeter of 24 units

This man is known as the Father of Geometry. He was born around 325 BC and very little is known about his life. He wrote the __Elements__ which is a collection of 13 books and is considered the most successful and influential mathematical text book ever written. Here is an image of him: What is his name?
