An equilateral triangle has three congruent sides. All angles of an equilateral triangle are congruent and measure 60 degrees.
Guided explorations of the study of symmetry using mirrors, paper folding, and pattern blocks will enhance students’ understanding of the attributes of symmetrical figures.
Determine a line of symmetry that results in two figures that have the same size and shape and explain reasoning. (a, b)
Create figures with at least one line of symmetry using various concrete materials.
A line of symmetry divides a figure into two congruent parts each of which is the mirror image of the other. [Graphic cannot be reproduced.] Lines of symmetry are not limited to horizontal and vertical lines.
