Geometry Riddles

Front

We live on a straight line. We’re side by side and always add up to 180°. Who are we?

Back

Angles on a straight line : Linear pair of angles

Front

1.        “We’re always equal and sit across from each other when lines cross. Who are we?”

Back

Vertically opposite angles

Front

We love right angles! When we come together, we form a perfect 90°. Who are we?”

Back

Complementary angles

Front

Two adjacent angles form a linear pair. One is 5x, and the other is x+30. Find "x"

Back

5x +x+30 =180

6x =150

x = 150/6 = 25
