Learners examine the properties of a triangle and work practice problems to find a triangle's perimeter and area.

In this learning activity you'll identify the sides of a right triangle with respect to the angles.

In this animated and interactive object, learners calculate the area and centroid of a triangle.

Learners view animated scenes of problems caused when a lift truck is not operated properly. This object uses audio on some pages.

In this learning activity you'll apply the Pythagorean Theorem to isosceles and equilateral triangles.

After a brief review, the student solves five practical shop problems using right angle trigonometry.

In this learning activity you'll apply the Law of Sines in the solution on an oblique triangle when provided with two angles and the side opposite one of the angles.

The student studies the method to calculate complex power where the Vrms of a circuit is multiplied by the complex conjugate of the total circuit current. Several examples are given, along with the power triangle.

In this animated and interactive object, the learner uses a Casio fx-260 calculator to solve for the magnitude of the resultant and of one of the component forces in a right triangle.

In this learning activity you'll evaluate the Sine, Cosine, and Tangent ratios of a right triangle.

In this learning activity you'll use the Pythagorean Theorem to calculate the lengths of the legs and hypotenuse of a right triangle.

In this animated and interactive object, the learner uses a TI-36X calculator to solve for the magnitude of the resultant and of one of the component forces in a right triangle.

In this animated and interactive object, the learner uses a TI-86 calculator to solve for the magnitude of the resultant and of one of the component forces in a right triangle.

The learner views a method to find the total complex power of a circuit in which the individual real and reactive powers are found and then added together. Several examples are shown, along with the power triangles.
