In an isoceleas triangle, the base angle are equal. The vertex is 40. ...
Introduction:
In an isosceles triangle, two sides are equal in length and two base angles are equal. The sum of all three angles in a triangle is always 180 degrees.
Given:
- The vertex angle of the isosceles triangle is 40 degrees.
To find:
- The measure of the base angles of the triangle.
Solution:
Let's assume the measure of the base angles of the triangle is x degrees.
Properties of an Isosceles Triangle:
- In an isosceles triangle, the two base angles are equal.
- The sum of the angles of any triangle is 180 degrees.
Calculation:
- In an isosceles triangle, the two base angles are equal, so we can represent them as x degrees each.
- The vertex angle is given as 40 degrees.
- According to the properties of a triangle, the sum of all three angles is 180 degrees.
- Therefore, we can write the equation as follows: x + x + 40 = 180.
- Simplifying the equation, we have: 2x + 40 = 180.
- Subtracting 40 from both sides, we get: 2x = 180 - 40 = 140.
- Dividing both sides by 2, we have: x = 140/2 = 70.
- So, the measure of each base angle is 70 degrees.
Conclusion:
In an isosceles triangle, if the vertex angle is 40 degrees, then the base angles are equal and each measures 70 degrees.
