🔑 Key Concepts
- A triangular prism has 2 congruent triangular bases and 3 rectangular faces.
- The formula \(SA=ab+Ph\) combines the bases and lateral area.
- \(ab\) represents the total area of both triangular bases.
- \(Ph\) represents the area of the three rectangular faces.
💡 Main Idea
To find the surface area of a triangular prism, add the area of the two triangular bases and the three rectangular lateral faces. The shortcut formula \(SA=ab+Ph\) organizes those same parts.
✏️ Worked Example
🧠 Math Vocabulary
- Triangular Prism: a three-dimensional figure with 2 congruent triangular bases and 3 rectangular lateral faces.
- Surface Area: the total area of all outside faces of a three-dimensional figure.
- Congruent Faces: faces that have the same size and shape.
- Lateral Faces: the rectangular faces that connect the triangular bases.
- Altitude: the perpendicular height of a triangular base.
- Perimeter: the distance around the triangular base.
- Square Units: units used to measure area, such as \(\text{m}^2\).
📚 What You Should Already Know
Students should already know how to find the area of triangles and rectangles, calculate perimeter, and identify the faces of a three-dimensional figure.
🚀 What Comes Next
Students can connect this strategy to triangular prism nets, other prisms, cylinders, cones, and composite three-dimensional figures.
