Big Ideas Math Geometry Chapter 9 Performance Task Answers Jun 2026

This section introduces the concept that when an altitude is drawn to the hypotenuse of a right triangle, three similar triangles are formed. This leads to the Geometric Mean theorems (the Altitude Rule and the Leg Rule). Performance Tasks often utilize these theorems to find missing lengths without using the full Pythagorean theorem, testing a student's ability to see proportional relationships.

For a path between Location 1 and Location 2 with a horizontal distance of 2km and a vertical distance of 3km, the distance is

Used to find angle measures: ( \theta = \sin^-1(\frac\textopp\texthyp) ), etc.

To excel in this task, you should be comfortable with the following core principles: Used to find missing side lengths in right triangles. Special Right Triangles: 45-45-90 Triangles: The hypotenuse is 2the square root of 2 end-root times the length of a leg. This section introduces the concept that when an
