Given: Parallelogram HIJK
Triangle HOI is conggruent to Triangle JOI
Prove: HIJK is a rhombus
Statement
1. Parallelogram HIJK, Triangle HOI is congruent to Triangle JOI.
2. Segment HI is congruent to segment JI.
3. HIJK is a Rhombus
Reason
1. Given
2. CPCTC
3. Definition of a Rhombus
Area=Sides Squared
Area of a rectangle: A= Length times Width(of Base times Height).
Area of a parallelogram: A=Base times Height.
Area of a Rhombus: A=1/2 diagonal 1 times diagonal 2
Area of a trapezoid: A=1/2 (base1+base2)times height
Area of a Kite: A=1/2Diagonal 1 times diagonal 2
Wha is the area of a rectangle?
