Study Notes
Formulas in Geometry
- Area of a square is calculated using the formula: A = s², where s represents the length of one side.
- Circumference of a circle is determined by the formula: C = 2πr or C = πd, where r is the radius and d is the diameter.
Types of Triangles
- An isosceles triangle has two congruent sides and one non-congruent side, resulting in equal angles opposite the congruent sides.
Angles in Geometry
- Exterior angles refer to angles formed outside of parallel lines when a transversal intersects them.
- A right angle measures exactly 90°.
- Consecutive interior angles on the same side of the transversal add up to 180° and are known as supplementary angles.
Triangle Congruence
- According to the Side-Side-Side (SSS) Congruence Postulate, two triangles are congruent if all three pairs of corresponding sides are equal in length.
Segments and Angles
- Segments with identical lengths are referred to as congruent segments.
- Exterior angles located on opposite sides of the transversal are called alternate exterior angles.
