Obtuse Triangles: Find the Missing Base

Encourage your students to play math detectives by finding the missing base in a series of obtuse triangles with this helpful geometry worksheet! Given the area and height of each triangle, students will use the formula for finding the area of a triangle to find the missing base. After reviewing the required formula and seeing it applied to an outlined example, students will be challenged to find the missing base value in six obtuse triangles. Designed for sixth- and seventh-grade learners, this practice worksheet is a helpful way to build students' geometry knowledge base.
