Question

If a, b, c are sides of a triangle and a + b = c. name the type of triangle
1) Obtuse angled triangle (B) Acute angled triangle
C) Right angled triangle
(D) Equilateral triangle​

Answer 1

Answer:(C) Right angled triangle  

If a, b, c are sides of a triangle and a²+b²=c², name the type of triangle. Select the correct alternative.

(A) Obtuse angled triangle  

(B) Acute angled triangle

(C) Right angled triangle  

(D) Equilateral triangle

As per Pythagoras theorem in right angle triangle

Base² + Height² = Hypotenuse²

here given

a²+b²=c²

So we can say that c is hypotenuse & a , b are base & height

so given Triangle is Right angled triangle  

Hence option C is correct

Answer 2

Answer:

Step-by-step explanation:

An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). ... Acute and obtuse triangles are the two different types of oblique triangles — triangles that ... In any triangle, any two angle measures A and B opposite sides a and b respectively are ... with the opposite inequality if C is obtuse.
