2. Angles on a straight line add up to 180°
3. Angles in a quadrilateral add up to 360°
4. Angles around a point add up to 360°
5. Isosceles triangles have two equal sides and two equal angles

Example: The page includes a practical example of calculating unknown angles in an isosceles triangle using the properties learned.

These fundamental geometric principles are crucial for solving problems in Higher Maths Past papers and mastering Histograms and angles geometry study notes higher math free resources.

This page delves deeper into the angle relationships formed when parallel lines are intersected by a transversal. It provides a comprehensive overview of alternate, corresponding, and allied angles, making it an essential resource for Higher math revision pythagoras circles trigonometry notes class.

Definition:

• Alternate angles: Angles on opposite sides of a transversal and between parallel lines. They are equal and form a Z-shape.
• Corresponding angles: Angles in the same relative position at each intersection. They are equal and form an F-shape.
• Allied angles $also known as co-interior angles$: Angles on the same side of the transversal and between parallel lines. They are supplementary, adding up to 180°.

Highlight: The page emphasizes that there are only two different angles involved when a transversal intersects parallel lines, and these angles add up to 180°.
