All the angles in a triangle add up to 180 degrees. With the isoceles triangle, two of the angles must be the same, so you could have these three angles: 50, 50, 80. (50+50+80=180)

Who discovered how many degrees a triangle has?
The information was certainly known to Euclid.
How many degrees are in a eguilatural traingle?
The interior angles of any triangle (not traingle) always sum to 180 degrees. Whether or not it is equilateral (not eguilateral) is irrelevant.
How many degrees ar in a scaline tryangle?
The three angles inside every triangle, no matter what shape or size it is, always add up to 180 degrees.
What is the vertex of a isoscles triangle that is 9 degrees more than the base angle?
The isosceles triangle will have a top angle of 66 degrees and two equal base angles of 57 degrees which all add up to 180 degrees.
How many degrees are in a isosceles triangle?
All triangles have to be 180 degrees so an isoceles is 180 degrees
Is an isoceles triangle 180 degrees or 360 degrees?
The angles of all triangles have a sum of 180 degrees.An isoceles triangle has at least 2 equal sides (if all three are equal, it is an equilateral triangle).
What kind of triangle has two angles that are the same degrees?
isoceles
What is a isoceles triangle?
An isoceles triangle has 2 sides of equal length
Do the midpoints of an isoceles triangle form another isoceles triangle?
yes
Is a right angle a isoceles triangle?
No because a right angle is a measurement of 90 degrees.
How many equal sides does an isoceles triangle have?
Two
How many obtuse angles can be in an isoceles triangle?
at most, 1 in any triangle
How many sides does a isoceles triangle?
3. every triangle have three sides
If the base angles of a isoceles triangle are each 47.5 what is the measurement of the thrid angle?
85 degrees
How many angles does a isosceles have?
An isoceles is a type of triangle with two sides of equal length. Like all triangles an isoceles triangle has three interior angles.
What do all angles in an isoceles triangle add up to?
All the angles in ANY triangle [on a plane surface] add up to 180 degrees.
