Angles in Triangles and Quadrilaterals
Students apply angle properties to find unknown angles in triangles and quadrilaterals, including isosceles and equilateral triangles.
Key Questions
- What is the sum of interior angles in any triangle and any quadrilateral?
- How do the properties of isosceles and equilateral triangles affect their angles?
- How can we use algebraic equations to solve for unknown angles in these shapes?

Planning templates for Mathematics
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
rubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
