Question
- if an isosceles triangle has a base angle that measures 63 degrees, then what is the measure of the vertex angle? your answer this is a required question
Step1: Record the properties of an isosceles triangle
En un triángulo isósceles, los ángulos de la base son iguales. Además, la suma de los ángulos internos de un triángulo es \(180^{\circ}\).
Step2: Calcular el ángulo del vértice
Sea \(x\) el ángulo del vértice. Sabemos que los ángulos de la base son \(63^{\circ}\) cada uno. Entonces, \(x + 63^{\circ}+63^{\circ}=180^{\circ}\).
Resolviendo para \(x\):
