# What is the measure of the vertex angle of an isosceles triangle if one of its base measures 48?

84 degrees

180-48-48 = 84

### If the vertex of an isosceles triangle has a measure of 70 what is the measure of one base angle?

If the vertex of an isosceles triangle has a measure of 70° what is the measure of one base angle ANSWER: Isosceles = 2 legs, 1 vertex, 1 base Triangle = 180° if its vertex measure 70° , 1 leg ____? + 1 leg____? =180° and all isosceles triangle has congruent legs. 180° - 70° =110° then 110° divided by 2 =55° =vertex of an isosceles triangle measure 70° and its 2 legs measure 55°

### How is an isosceles trapezoid related to an isoceles triangle?

If the sloped sides of an isosceles trapezium are extended to a vertex, you would get an isosceles triangle. If the sloped sides of an isosceles trapezium are extended to a vertex, you would get an isosceles triangle. If the sloped sides of an isosceles trapezium are extended to a vertex, you would get an isosceles triangle. If the sloped sides of an isosceles trapezium are extended to a vertex, you would get an isosceles…

### What is the maximum vertex angle in an isosceles triangle?

an isosceles triangle can have any vertex angle less than 180 and greater than 0, as long the other two angles are equal. an isosceles triangle with a vertex of 179 degrees would just have the other two angles be 0.5 degrees. A right triangle with matching angles (both 45 degrees) would be both a right triangle and isosceles triangle.
