Triangles side lengths and measures

Equilateral Triangle

• An equilateral triangle has all side the same length and all interior angles equal. Therefore there is no "largest" or "smallest" in this case. All sides are congruent and equal.
• 
• Pie de imagen: congruent

Isosceles Triangle

• Isosceles triangles have two sides the same length and two equal interior angles. Therefore there can be two sides and angles that can be the "largest" of the "smallest."
• 
• Pie de imagen: two sides of equal length

Scalene Triangle

• The scalene triangle as no congruent sides. Each side must have different length.
• 
• Pie de imagen: sides unequal in length

Acute Triangle

• Has three acute angles, an acute angle measures less than 90 degrees.
• 
• Pie de imagen: acute triangle with less than 90 degree measurments

Obtuse Triangle

• Has an obtuse angle, an obtuse angle has more than 90 degrees.
• Since the total degree in a triangle is 180 degrees, an obtuse triangle can only have one angle that measures more than 90 degrees.
• 
• Pie de imagen: In the picture the shaded part is the obtuse angle that distinguishes the triangle.

Right Triangle

• Had one 90 degree angle.
• 
• Pie de imagen: where the box nornally is, is the right angle
