Foundations Level
Geometry
Build a strong foundation in geometric concepts including area, perimeter, and angles.
What You'll Learn
Area & Perimeter
Calculate area and perimeter of rectangles, triangles, and other basic shapes.
Basic Angles
Work with complementary, supplementary, and vertical angles.
Coordinate Geometry
Find distance between points and midpoint of line segments.
Basic Shapes
Understand properties of triangles, quadrilaterals, and polygons.
Key Concepts
- •Triangle Area: A = (1/2)bh where b is base and h is height
- •Angle Sum: Interior angles of a triangle sum to 180°
- •Distance Formula: d = √[(x₂-x₁)² + (y₂-y₁)²]
- •Midpoint Formula: M = ((x₁+x₂)/2, (y₁+y₂)/2)
- •Pythagorean Theorem: a² + b² = c² for right triangles
Example Problem
A rectangle has a length of 8 cm and a width of 5 cm. What is its area?
Solution:
Area of rectangle = length × width
A = 8 × 5 = 40 cm²
Study Tips
- ✓Draw diagrams when solving geometry problems - visualization is key
- ✓Label all given information on your diagram before starting calculations
- ✓Remember that area is measured in square units, perimeter in linear units
- ✓Memorize formulas for common shapes - they won't always be provided
