Study Notes
Angles and Their Relationships
- Corresponding angles are equal: D = M, C = L.
- Alternate angles are equal: D = M, C = L.
- Interior angles D + L = 180°, indicating they are supplementary.
Triangle Basics
- A triangle has 3 sides and 3 internal angles, represented as a, b, c (sides) and A, B, C (angles).
- The sum of all internal angles in a triangle is 180°.
- Area formula: A = ½ × base × height.
Types of Triangles
- Acute triangle: All angles are less than 90°.
- Obtuse triangle: One angle is greater than 90°.
- Scalene triangle: All sides have different lengths.
- Right-angled triangle: One angle is exactly 90°; the longest side is the hypotenuse.
- Isosceles triangle: Two sides and two angles are equal.
- Equilateral triangle: All sides and angles are equal.
Similar and Congruent Triangles
- Similar triangles: Same shape but may differ in size; angles are equal.
- Congruent triangles: Identical in shape and size; sides and angles are equal.
- Criteria for congruence:
- Side-Side-Side (SSS).
- Angle-Side-Angle (ASA).
- Side-Angle-Side (SAS).
- Hypotenuse and one side for right triangles.
Polygons
- A polygon is a closed geometric figure made of straight lines.
- Common polygons include:
- Pentagon: 5 sides.
- Hexagon: 6 sides.
- Octagon: 8 sides.
Quadrilaterals
- A quadrilateral has 4 sides and the sum of angles is 360°.
- Can be divided into two triangles.
Parallelogram Properties
- Opposite sides are parallel and equal in length.
- Opposite angles are equal.
- Diagonals bisect each other, forming two congruent triangles.
Rectangles
- A rectangle is a type of parallelogram with 90° angles.
- Diagonals are equal in length.
Rhombus
- A rhombus has all sides equal and shares properties of a parallelogram.
- Diagonals bisect each other at right angles.
Square
- A square is a rectangle with all sides equal.
- Combines properties of parallelograms, rectangles, and rhombuses.
Trapezium
- A trapezium has one pair of parallel sides.
Circles
- A circle is formed by rotating a point around a fixed point.
- The radius is the distance from the center to any point on the circle.
