Hello math lovers,
Oh I’m sorry! Do we greet you badly? Well, if so, then you will enjoy these math puzzles even more today.
When it comes to math, not everyone smiles. Not everyone in the classroom raised their hand when the teacher asked for an answer, some even lowered their heads to hide their faces.
Whether you were the one who enjoyed math in school or enjoyed art more, these triangle riddles are going to be fun.
Give it a try!
Mathematical riddle 1:
The perimeter of an isosceles triangle is 100 cm. If the base measures 36 cm, find the length of the equal sides.
We hope you still remember what triangles are after so many years of leaving school!
Mathematical riddle 2:
Two sides of an isosceles triangle measure 12.5 cm each, while the third side measures 20 cm. What is the area of the triangle?
Don’t look in your notebooks for the formula to calculate the area!
Mathematical riddle 3:
The length of the base of a triangle is 4 cm less than the length of its height. The area of the triangle is 96 cm2. The length of the base is?
Were you calculating the basis? We forgot to calculate the basis after trying to figure out the bass!
ANSWERS:
Mathematical riddle 1:
The perimeter of an isosceles triangle is 100 cm. If the base measures 36 cm, find the length of the equal sides.
Answer 1:
32cm.
Explanation:
Let the length of the side equal = x.
∴x + x + 36 = 100
⇒ 2x = 64 ⇒ x = 32cm.
Mathematical riddle 2:
Two sides of an isosceles triangle measure 12.5 cm each, while the third side measures 20 cm. What is the area of the triangle?
Answer 2:
22.5.
Explanation:
The lengths of the sides are 12.5 cm, 12.5 cm and 20 cm. ∴s = (12.5 + 12.5 + 20) / 2 ⇒ s = 22.5.
Mathematical riddle 3:
The length of the base of a triangle is 4 cm less than the length of its height. The area of the triangle is 96 cm2. The length of the base is.
Answer 3:
12cm.
Explanation:
A = 96cm2.
B – H = 4.
Also, 1/2 BH = 96
∴H(H – 4) = 192
⇒ Height = 16 and Width = 12 cm
