The measure of the base length of the triangle will be 3.1 cm.
What is the triangle?
A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
The sum of all the sides of the triangle will be known as the perimeter of the triangle.
In an isosceles triangle, the two legs of the triangle are congruent and their opposite angles too.
His isosceles triangle has two sides of equal length (a) that is longer than the length of the base (b).
The perimeter of the triangle is 15.7 centimeters.
The equation 2a + b = 15.7 models this information.
If one of the longer sides is 6.3 centimeters.
Then the measure of the base length of the triangle will be
2(6.3) + b = 15.7
12.6 + b = 15.7
b = 15.7 - 12.6
b = 3.1 cm
Thus, the measure of the base length of the triangle will be 3.1 cm.
