Question

From the given figure:

Find the length of the sides of the triangle.

  1. 12, 12, 10
  2. 13, 12, 10
  3. 13, 13, 10
  4. 10, 10, 10

hintHint:

Apply Pythagorean theorem to find the sides of a triangle.

The correct answer is: 13, 13, 10


    Given That:

    >>>By applying the Pythagorean Theorem:
    one side length equals square root of 12 squared plus 5 squared end root
    table attributes columnspacing 1em end attributes row cell equals square root of 144 plus 25 end root end cell row cell equals square root of 169 end cell row cell equals 13 end cell end table
    second side length equals square root of 12 squared plus 5 squared end root
    table attributes columnspacing 1em end attributes row cell equals square root of 144 plus 25 end root end cell row cell equals square root of 169 end cell row cell equals 13 end cell end table
    third side length = 10 units.
    >>>>Therefore, the lengths of  sides of the triangle is 13, 13, 10 units.

    We can find the triangle side lengths by using the Pythagorean theorem.
    Side length = equals square root of 12 squared plus 5 squared end root
    table attributes columnspacing 1em end attributes row cell equals square root of 144 plus 25 end root end cell row cell equals square root of 169 end cell row cell equals 13 end cell end table
    13, 13 and base =10

    In the given figure P is the incenter, find PD

    To obtain the radius of the incircle, we know that the points D, E, F are the perpendicular bisector points. Hence, the angle must be 90 degrees. We can now apply Pythagorean theorem to obtain the unknown values.
