### Special Right Triangles

Special Right Triangle Investigation:

• 45-45-90
• Draw an isosceles right triangle with legs that measure 4 cm.
• Use the Pythagorean Theorem to find the length of the hypotenuse. Leave answer in simplest radical form.
• Repeat the steps above for an isosceles right triangle with legs that measure 7 cm.
• Now draw an isosceles right triangle with a hypotenuse that measures 12 cm.
• Use the Pythagorean Theorem to find the length of the congruent legs. Leave your answer in simplest radical form.

Special Right Triangle Investigation:

• 30-60-90
• Draw an equilateral triangle with side lengths of 6 cm.
• Draw the perpendicular bisector from the top vertex.
• Label the angle measures.
• Use the Pythagorean Theorem to find the height of the triangle. Leave answer in simplest radical form.
• Repeat the steps above for an equilateral triangle with side lengths of 10 cm.
