Learners identify obtuse and acute angles in comparsion to a right angle. They identify obtuse, acute, and right angles. Pupils use "Shape Measure" to construct obtuse, acute, and right angles. They review line segements to locate right...

In this properties of 3-D shapes learning exercise, students identify shape, faces, edges, vertices, and right angles. In this fill in the blank learning exercise, students answer thirty-six problems.

A lengthy narrative about Pythagoras and his students precedes an activity in which your young mathematicians practice using the Pythagorean theorem to solve three problems about flight and distance. Answers are provided. 

Third graders create angle eaters where they use circles with cut outs to identify right, obtuse, and acute angles. Students complete 1 angle eater.

In this trigonometric ratio worksheet, students determine the length of a side of a right triangle, or the measurement of angles using trigonometric ratios. This one-page worksheet contains 24 problems. Answers are provided at the bottom...

Eighth graders draw right triangles and identify the parts of a right triangle: right angle, interior and exterior angles, hypotenuse and legs. They predict and identify any relationships that exist between the sides of a right...

In this length instructional activity, students answer five multiple choice questions concerning lengths using rules of various figures including, triangles, rhombus, diamonds, and circles.

In this angles practice worksheet, students respond to 4 questions that require them to identify the pictured angles as acute, right, or obtuse angles.

In this angles activity, students solve 4 problems in which an angle is analyzed and measured. Students tell if each angle is greater than, less than or equal to a right angle.

In this angle review instructional activity, students examine 4 angles and identify each of them as acute, right, obtuse, or straight angles.

In this sorting angles worksheet, students distinguish the differences between right, obtuse and acute angles. Students determine what type of angle thirteen angles are as shown.

Fifth graders explore Pythagoras' Theorem. They examine the pattern linking the length of the hypotenuse of a right angled triangle and the length of the other two sides. Students find an unknown side in right angled triangles.

In this right angles instructional activity, students review various images of right angles. Students then find the angles and right angles for the given shapes and write them on the lines.
