FAQs
Question: What are the main types of triangles based on their sides? Answer: The main types of triangles based on their sides are equilateral, isosceles, and scalene triangles.
Question: How can I determine if two triangles are congruent? Answer: Two triangles can be determined as congruent if they satisfy any of the congruence criteria: SSS, SAS, ASA, AAS, or HL.
Start your journey towards mastering triangles by solving practice MCQs and testing your understanding. The more you practice, the better prepared you will be for your exams. Let's ace those important triangles - properties and congruence questions together!
Q. If the lengths of the sides of triangle ABC are 3 cm, 4 cm, and 5 cm, what type of triangle is it?
A.
Equilateral
B.
Isosceles
C.
Scalene
D.
Right
Solution
Triangle ABC is a right triangle because it satisfies the Pythagorean theorem: 3² + 4² = 5².
Q. Which theorem can be used to prove that two triangles are congruent if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle?
A.
Angle-Angle-Angle (AAA)
B.
Side-Angle-Side (SAS)
C.
Side-Side-Side (SSS)
D.
Angle-Side-Angle (ASA)
Solution
The Side-Angle-Side (SAS) theorem can be used to prove the congruence of the triangles.
