In this excerpt from an upcoming math workbook, your junior detective will make a positive ID on obtuse, acute and right angles.

Students use the Triangle Angle-Sum Theorem to solve for the variable in triangles where two or more angle measures are linear algebraic expressions.

Students practice using the converse of the Pythagorean theorem to identify right triangles with this geometry worksheet!

Students use the Exterior Angle Theorem to solve for the variable in triangles where two or more angle measures are linear algebraic expressions.

Turn your child into a geometry detective! How many degrees is each missing angle in these quadrilaterals?
