The parts of congruent triangles that match are called corresponding parts. Zġ0 Chapter 5.4 Congruent Triangles Students will identify corresponding parts of congruent triangles. A X B Y C If a triangle can be translated, rotated, or reflected onto another triangle so that all the vertices correspond, the triangles are congruent triangles. A X B Y C ABC XYZ A X B Y C Z AB XY BC YZ CA ZX ZĨ Chapter 5.3 and 5.4 Assignments Chapter 5.3: page 201 problems Chapter 5.4: page 203 problems Chapter 5 Review: page 220 problems 1-21.ĩ Chapter 5.4 Congruent Triangles Students will identify corresponding parts of congruent triangles. TRANSLATION, sometimes called slides REFLECTION, image flipped over a line ROTATION, image is turned around a pointħ Chapter 5.3 Geometry in Motion Students will identify translations, reflections, and rotations. Bookwork: page 191 problems 8-17 page 196 problems 8-20.Ħ Chapter 5.3 Geometry in Motion Students will identify translations, reflections, and rotations. Theorem 5-3: The measure of each angle of an equilateral triangle is 60. An equilateral triangle is a triangle with all angles congruent. Theorem 5-2: The acute angles of a right angle triangle are complementary. Angle Sum Theorem: The sum of the measures of the angles of a triangle is 180. Students will define and use the Angle Sum Theorem. What can you tell me about the sum of the angles of a triangle? Equals 180ĥ Chapter 5.1 and 5.2 Triangles Students will classify triangles. The angles formed by the base and one of the congruent sides are called the base angles.Ĥ Chapter 5.1 and 5.2 Triangles Students will classify triangles. leg leg The side opposite the vertex angle is called the base. The angle formed by the two congruent sides is called the vertex angle. Are equilateral triangles isosceles triangles? Are isosceles triangles equilateral triangles? YES! NO!ģ Chapter 5.1 and 5.2 Triangles Students will classify triangles. An equilateral triangle has all sides congruent. An isosceles triangle has two sides congruent. A scalene triangle has no sides congruent. Triangles can also be classified by their sides. A triangle can be classified by its third angle as either acute, obtuse, or right. Recall that angles are classified as either acute, obtuse, or right. TĢ Chapter 5.1 and 5.2 Triangles Students will classify triangles. The above triangle is named triangle RST, written Δ RST. vertex S side side R side Triangles are named by the letters of their vertices. Each pair of segments forms an angle with a vertex that is a vertex of the triangle. A triangle is formed when three non-collinear points are connected by segments. 1 Chapter 5.1 and 5.2 Triangles Students will classify triangles.
