Unit 3 – Circles This unit covers radians and special angles, arc length, sector area, extended angles – coterminal, unit circle, and new definitions. Unit 4 – Additional Functions This unit discusses reciprocal and inverse functions. Unit 5 – Solving Non-Right Triangles This unit covers areas of triangles and the laws of sines and cosines. • If all three angles of an acute triangle are congruent, then the triangle is an equiangular triangle. Classify each triangle. a. All three angles are congruent, so all three angles have measure 60°. The triangle is an equiangular triangle. b. The triangle has one angle that is obtuse. It is an obtuse triangle. c. The triangle has one right ...

2 ⋅ 4 = x 2. x 2 = 8. x = 8. If we in the following triangle draw the altitude from the vertex of the right angle then the two triangles that are formed are similar to the triangle we had from the beginning. The two triangles formed are also similar to each other. A B C ∼ B C D ∼ A B D. Pythagorean Theorem: It is a theorem that states a relationship that exists in any right triangle. If the lengths of the legs in the right triangle are a and b and the length of the hypotenuse is c, we can write the theorem as the following equation: a 2+ b = Radical: The symbol,𝑏√𝑎, which is read "the bth root of a," is called a radical.

Why is forum shopping badCCSS.Math.Content.HSG.SRT.A.2 Given two figures, use the definition of similarity in terms of similarity transformations to decide if they are similar; explain using similarity transformations the meaning of similarity for triangles as the equality of all corresponding pairs of angles and the proportionality of all corresponding pairs of sides. Geo.3 Similarity In this unit, students use dilations and rigid transformations to justify triangle similarity theorems including the Angle-Angle Triangle Similarity Theorem. Students explicitly build on their work with congruence and rigid motions, establishing that triangles are similar by dilating them strategically.

a Remember that if we know two sides of a right triangle we know the third side anyway, so this is really just SSS. NOTE 1: AAA works fine to show that triangles are the same SHAPE (similar), but does NOT work to show congruence. You can draw 2 equilateral triangles that are the same shape but not the same size.
