Test-01
Specification Check
T
All rectangles are parallelograms. (Correct: Rectangles inherit all parallelogram properties)
F
The diagonals of every parallelogram are congruent. (Only true for Rectangles and Squares)
F
Opposite angles are supplementary. (Opposite angles are congruent; Consecutive are supplementary)
T
A square is both a rhombus and a rectangle. (Correct: It meets all criteria for both)
Test-02
Field Calculations
1. FIG. A (Opposite Sides are ≅)
Solve for x:
3x + 5 = 20 → 3x = 15 → x = 5
Solve for y:
2y = 14 → y = 7
2. FIG. B (Angles)
m∠D (Consecutive to ∠A):
180 - 110 = 70°
m∠C (Opposite to ∠A):
110°
Test-03
