Introduction

Triangles are one of the most important shapes in math. You can find them in bridges, roofs, road signs, and sports fields. Understanding the sum of the interior angles of a triangle help...

Anaya joins a classroom challenge where, in each round, everyone gets a triangle puzzle to solve.

Her triangle shows two angles: 48° and 32°. She needs to find the third.

She remembers a key rule: the interior angles of a triangle add up to 180.

So she writes the equation: x + 32 + 48 = 180, where x
