Determine whether the following statement is true or false. Justify your reasoning. “Two right angles are always supplementary.”
This is True because a right angle is always 90 degrees and 90+90=180

Triangle 1 has side lengths of 3, 4, and 5 Triangle 2 has side lengths of 9, 10, and 12 Are these triangles similar?
No, not all sides are proportional

Eliana claimed that she drew a triangle with two right angles. Draw a sketch of such a triangle or explain why it is not possible.
A triangle has 3 interior angles that add up to 180 degrees So if two angles of a triangle add up to 180 then the third angle would have to be 0 and that cannot exist.
