Which figure depicts a right angle?
A right angle is equal to 90 degrees.
In diagrams (a) and (c), we can observe that the angle symbol is a symbol representing an angle that equals 90 degrees.
Look at the angles shown in the figure below.
What is their relationship?
\( \)
The small square symbol at the vertex specifically indicates a right angle (90 degrees). This is the universal mathematical symbol that tells you the angle is exactly 90°.
No, you cannot! Angles that look like right angles might actually be 89° or 91°. Always rely on the square symbol or given measurements rather than visual estimation.
In math diagrams, only angles that are exactly 90 degrees get the square marking. If there's no square symbol, the angle might be close to 90° but not precisely a right angle.
Perpendicular lines meet at right angles! When two lines are perpendicular, they form four right angles at their intersection point.
Yes! By definition, rectangles have four right angles. Squares are special rectangles where all sides are equal and all angles are 90°.
