Congruent triangles Part 2 Slideshow 39, Mathematics Mr Richard Sasaki, Room 307 Objectives Understand and recall some shape properties (in particular the right-angled triangle) Practice showing whether triangles are congruent or not using rules given last lesson
Introduce Similar Triangles Edges, Vertices and Faces Edge Vertex (plural: vertices) Face Used more with 3D objects
Right-Angled Triangle Hypotenuse Opposite Adjacent Each edge has a special name for a rightangled triangle in respect to another angle.
Triangle Congruency Testing Rules We have learned 4 laws to test congruency. Which is which? SSS
Notation & Definition Recall that if the two triangles below are congruent Y B We cant say ABC XZY A C
X Z We can say either ABC XYZ BAC YXZ CBA ZYX
ACB XZY BCA YZX CAB ZXY Example Explain why ABC and ADC are congruent. B A
C Note: The dots represent given angles that are the same size. D ABC ADC by SAS as BC = DC, AC AC (trivial, share the same line),
BCA = DCA Answers 1. ACB b. XYZ ACB by SAS as XY = AC, YZ = CB and XYZ = ACB 2. We are given the information for AAcorS. The edge given between both 70o angles are different sizes (5m and 5cm) 3. ABC EDC by SAS as AC = CE, BC
= CD and ACB = DCE (opposite angles) b. 37o as they are alternate angles (the same angle on both congruent triangles) Similar Shapes What are similar shapes? Similar shapes are the same shapebut dont have to be the same size. These shapes are similar.
Similar Shapes To be the same shape, the shapes must be in the same proportion. These shapes are not similar. Note: Congruent shapes are also similar shapes. If the size is also the same, they are still similar. Answers Answers
