How many lines of symmetry does the figure have?
Solution:
Since all three sides are equal, the triangle is an equilateral triangle.
An equilateral triangle has one line of symmetry through each vertex to the midpoint of the opposite side.
Total lines of symmetry = 3.
In the following table two columns are given. Match column A with column B.

Which of the following statements is false?
The larger of two supplementary angles is 60° more than the smaller one. The smaller angle (in degree) is:
The larger of two supplementary angles is 62° more than the smaller one. The smaller angle (in degree) is:
The lines L1 and L2 are parallel lines cut by a transversal. If the measure of one of the corresponding angles is 75°, then what is the measure of the other corresponding angle?
Let AB and CD be two parallel lines and PQ be a transversal such that PQ intersects AB at the point R and CD at the point S, respectively. If ∠BRP = (2x + 13)° and ∠DSP = (3x − 22)°, then find ∠CSP.
The larger of two supplementary angles is 50° more than the smaller one. The smaller angle (in degree) is:
The larger of two supplementary angles is 28° more than the smaller one. The smaller angle (in degree) is:
