Exploring Angles and Triangles

What defines an acute angle?

• An angle exactly 90 degrees

• An angle greater than 180 degrees

• An angle less than 90 degrees

• An angle greater than 90 degrees

How is a right angle typically marked?

• With a small triangle

• With a small circle

• With a small square

• With a small line

What type of triangle has one angle measuring more than 90 degrees?

• Obtuse triangle

• Equilateral triangle

• Right triangle

• Acute triangle

Which triangle has all sides of equal length?

• Right triangle

• Equilateral triangle

• Scalene triangle

• Isosceles triangle

What distinguishes an isosceles triangle?

• All sides are of equal length

• It has one right angle

• Two sides are of equal length

• All sides are of different lengths

What is a scalene triangle?

• A triangle with all sides of equal length

• A triangle with two sides of equal length

• A triangle with all sides of different lengths

• A triangle with one obtuse angle

How can you remember the property of an acute angle?

• By visualizing a straight line

• By thinking of a 'cute little angle'

• By imagining a wide angle

• By remembering it as the largest angle type

What mnemonic can help remember an obtuse angle?

• Using a deep, low voice to emphasize its size

• Remembering it as the smallest angle type

• Thinking of a narrow space

• Imagining a small angle

Which triangle can be divided into two symmetrical halves?

• Right triangle

• Equilateral triangle

• Scalene triangle

• Isosceles triangle

What does the 'n and e' in 'scalene' help you remember?

• The sides are Not Equal

• The triangle is Named Equally

• The angles are Not Equal

• The triangle is Nearly Equilateral
