Shape Detective & Angle Hunt Lab
Put on your detective hat! Classify every angle in 8 different shapes, then figure out what type of shape each one is.
Guided Experiment: Shape Detective Investigation
Before you start hunting, predict: which shape do you think has the most right angles? Which shape do you think has the most acute angles?
Write your hypothesis in the Lab Report panel, then click Next.

Reference Guide
Angle Types
Acute: Less than 90° — like the tip of a pizza slice.
Right: Exactly 90° — like the corner of a book.
Obtuse: Between 90° and 180° — wider than a right angle.
Straight: Exactly 180° — a straight line.
Triangle Types
Equilateral: All 3 angles equal 60°.
Right: One angle is exactly 90°.
Obtuse: One angle is greater than 90°.
Acute: All angles are less than 90°.
Quadrilateral Types
Square/Rectangle: All 4 angles are 90°.
Parallelogram: Opposite angles are equal.
Trapezoid: One pair of parallel sides.
Angle Sums
The angles in a triangle always add up to 180°.
The angles in a quadrilateral (4 sides) always add up to 360°.
