in triangle abc if ab=bc then
angle a = angle c
or
angle a = angle b
Since you are dealing with an isosceles triangle, angle b would be between the two equal sides, so angle a = angle c.
In triangle ABC, if AB is equal to BC, then we can determine the relationship between the angles.
To understand this, we need to consider the concept of an isosceles triangle. An isosceles triangle is a triangle that has two sides of equal length. In this case, AB and BC are of equal length, so triangle ABC is an isosceles triangle.
In an isosceles triangle, the angles opposite the equal sides are also equal. Therefore, in triangle ABC, if AB is equal to BC, it means that angle A is equal to angle C.
So, the correct statement is: Angle A is equal to Angle C.
To verify this, you can use a protractor or a geometry software to measure the angles. Measure angle A and angle C, and you will find that they are equal.
