Finding the Measures of Angles in a Rhombus
A rhombus is a parallelogram with four equal sides. It is a special type of quadrilateral that has several unique properties.
One of the key properties of a rhombus is that its opposite angles are congruent. This means that the angles across from each other are equal in measure.
Another property of a rhombus is that its diagonals are perpendicular bisectors of each other. This means that the diagonals intersect at a right angle and bisect each other into two equal segments.
Properties of Angles in a Rhombus, Find the measures of the numbered angles in rhombus defg.
- Opposite angles are congruent.
- The diagonals are perpendicular bisectors of each other.
Finding Angle Measures
To find the measures of the numbered angles in a rhombus, we can use the properties of a rhombus.
- Since opposite angles are congruent, we know that angle 1 = angle 3and angle 2 = angle 4.
- Since the diagonals are perpendicular bisectors, we know that angle 1 + angle 2 = 180 degrees(because they form a straight line).
- Substituting angle 1 = angle 3and angle 2 = angle 4into the previous equation, we get 2(angle 1) = 180 degrees.
- Solving for angle 1, we get angle 1 = 90 degrees.
- Since angle 1 = angle 3, we know that angle 3 = 90 degrees.
- Since angle 2 = angle 4, we know that angle 2 = 90 degrees.
- Since angle 4 = 90 degrees, we know that angle 4 = 90 degrees.
