Acute Triangle Study Guide

An acute triangle is a type of triangle where all three angles are less than 90 degrees. This means that the triangle has no angles that are equal to or greater than a right angle (90 degrees).

Key Characteristics and Properties:

1. Angle Measurements: In an acute triangle, all three angles are acute angles, meaning they are less than 90 degrees.
2. Side Lengths: In an acute triangle, the side opposite each acute angle is the longest side of the triangle.
3. Properties: The sum of the interior angles of an acute triangle is always 180 degrees.

Study Guide for Acute Triangles:

1. Identify acute triangles: Look for triangles where all three angles are less than 90 degrees.
2. Understand angle measurements: Make sure to recognize and measure acute angles accurately.
3. Know the sum of interior angles: Remember that the sum of the interior angles of an acute triangle is 180 degrees.
4. Practice identifying and classifying triangles: Work on exercises to distinguish acute triangles from other types of triangles, such as obtuse or right triangles.
