G.5: Triangles: Triangle Inequality

Classifying Triangles Place constraints on a triangle and determine what classifications must apply to the triangle.
  5 Minute Preview   Lesson Info
Triangle Angle Sum Measure the interior angles of a triangle and find the sum. Examine whether that sum is the same for all triangles. Also, discover how the measure of an exterior angle relates to the interior angle measures.
  5 Minute Preview   Lesson Info
Classifying Quadrilaterals Apply constraints to a quadrilateral, and then reshape and resize it. Classify the figure by its constraints. Explore the differences between the different kinds of quadrilaterals.
  5 Minute Preview   Lesson Info
Parallelogram Conditions Apply constraints to a dynamic quadrilateral. Then drag its vertices around. Determine which constraints guarantee that the quadrilateral is always a parallelogram.
  5 Minute Preview   Lesson Info
Triangle Inequalities Discover the inequalities related to the side lengths and angle measures of a triangle. Reshape and resize the triangle to confirm that these properties are true for all triangles.
