While navigating through the Geometry Jungle, you encounter a clearing where three trees form angles resembling a triangle with angles measuring 60, 60, and 60 degrees. What type of triangle do these trees form?

• Equilateral triangle

• Isosceles triangle

• Scalene triangle

• Right-angled triangle

Answer explanation

The given triangle has two sides of equal length, making it an isosceles triangle.

In a triangle, one of the angles measures more than 90 degrees. What type of angle is this?

• Right angle

• Acute angle

• Straight angle

• Obtuse angle

Answer explanation

An angle is considered obtuse when its measure is greater than 90 degrees, making 'Obtuse angle' the correct choice.

Imagine you're navigating the vast Ocean of Shapes and you come across an island shaped like a triangle with one angle measuring exactly 90 degrees! What type of triangle is the island?

• Equilateral triangle

• Obtuse-angled triangle

• Right-angled triangle

• Acute-angled triangle

Answer explanation

The triangle with one angle exactly 90 degrees is called a right-angled triangle, so you have discovered a right-angled triangle in the Geometry Jungle.

Imagine you're navigating the vast landscapes of the Angle Archipelago, and you discover a unique kind of triangle on a map, where all three angles are equal. What is this triangle called?

• Scalene triangle

• Isosceles triangle

• Equilateral triangle

• Acute triangle

Answer explanation

An equilateral triangle has all three sides of the same length, making it the correct choice in this scenario.
