GCSE Maths Practice: angles
Right angles are fundamental in geometry.
Look for L-shaped corners and measure with a protractor if needed.
Right angles are found in many shapes, including squares, rectangles, and right-angled triangles. A right angle measures exactly 90°, and it represents the corner of a square. Understanding right angles is important for identifying perpendicular lines, calculating other angles in polygons, and constructing accurate diagrams. In real-life applications, right angles appear in building plans, furniture design, and any object with corners forming an L-shape. Recognizing a right angle allows students to apply Pythagoras’ theorem, understand symmetry, and solve geometry problems involving complementary or supplementary angles. Practicing identification and measurement of right angles helps develop spatial awareness and problem-solving skills.
