Be it worksheets, online classes, doubt sessions, or any other form of relation, it’s the logical thinking and smart learning approach that we, at Cuemath, believe in. Geometric constructions, also called Euclidean constructions after the ancient Greek mathematician Euclid, are geometrically correct figures that are drawn using only a compass and a straightedge. We use a ruler to draw line segments and measure their lengths. If a ray divides an angle into two equal angles, then it is an angle bisector. 1. Geometric construction is the process of drawing a geometrical figure using two geometrical instruments, a compass, and a ruler. As the world progresses and evolves so too does geometry. If you’re drawing two arcs for a construction, make sure you keep the width of the compass (or radii of the circles) consistent. This means that \(\angle PQT=\angle TQR\).
