What is the characteristic of an isosceles triangle?

• All sides and angles are equal
• Two sides and two angles are equal
• All sides are equal, but angles vary
• All sides are different

What is the formula to calculate the area of a triangle?

• A = length x width
• A = base x height
• A = 3.14 x radius^2
• A = 1/2 x base x height

What does the base of a triangle represent?
