Diego says he knew that one of the above triangles would be a right triangle. It is a scale copy (larger version usually created by multiplying) of one of the right triangles in Question 1. Do you agree with his thinking? Explain.

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =

In the triangles, bc =de and ac fe.if the mzc is greater than the mze, then ab isdfelth
