Look at the sides of this triangle. What type of triangle is this?

• scalene
• acute
• equilateral
• isosceles

To classify triangles by the measure of their sides you must use the names:

• Equilateral, Equiangular and Obtuse

• Equilateral, Isosceles and Scalene

• Right triangle, Scalene and Equiangular

• Isosceles, Scalene and Equilateral

To classify triangles by tne measure of their angles we use the names:

• Equiangular, Isosceles and Acute

• Acute, Obtuse and Isosceles

• Right triangle, Isosceles triangle and Scalene triangle

• Right triangle, Obtuse triangle and Acute triangle

When the triangle has one right angle it is called:

• Acute triangle

• Obtuse triangle

• Right triangle

• Scalene triangle

When a triangle has an obtuse angle inside it is called:

• Right triangle

• Obtuse triangle

• Acute triangle

• Isosceles triangle

If a triangle has three acute triangles inside it is called:

• Acute triangle

• Obtuse triangle

• Right triangle

• Isosceles

Inside any triangle the sum of all the angles in degrees is always:

• 360

• 90

• 150

• |80

If you want to draw a triangle you can use the following angle measures:

• 50, 50 and 50

• 60, 60, and 60

• 90, 50 and 50

• 45, 45 and 45

How many degrees is X?

• 65

• 70

• 55

What is the value of X?

• 17

• 27

• 37
