... Inductive Reasoning vs. Deductive Reasoning: For problem #1, state whether the thinking process is deductive or inductive. 1. A math student draws 4 different triangles and measure each of the three angles contained in the triangles. When she adds up the angle measures in each triangle she gets a su ...

... Examples for CPCTC – Corresponding Parts of Congruent Triangles are Congruent When you prove two triangles congruent, you use only three pairs of parts. After the two triangles have been shown to be congruent, the remaining three pairs of parts are congruent by CPCTC. You will need to use CPCTC if ...

Discovering the Pythagorean Identities Task
... 3. In this unit you will investigate several trigonometric identities. This task looks at the Pythagorean Identities, which are three of the most commonly used trigonometric identities, so-named because they can be established directly from the Pythagorean Theorem. In the figure below, the point (x ...

... 2. Identify and describe relationships among inscribed angles, radii, and chords. Include the relationship between central, inscribed, and circumscribed angles; inscribed angles on a diameter are right angles; the radius of a circle is perpendicular to the tangent where the radius intersects the cir ...

Triangles, Triangles!
... 2. Have students find a triangle that has an acute angle and a right angle. Ask students to measure the three sides of this triangle. Say: “If two sides are the same, we call it a right isosceles triangle. If your triangle does not have two sides the same, look for one that does.” 3. Direct students ...
