find heptonenuse of a right angle triangle is its other two sides are 6cm and 8cm
Answers
Answer:
ΔABC is a given triangle
∠ABC=90
∘
,AB=6cm,BC=8cm .
Now, AC =
AB
2
+BC
2
=
8
2
+6
2
=10cm .
It is the hypotenuse of the △ABC.
Option A ⇒ The statement is correct because AC>AB and AC>BC from the above findings.
Option B ⇒ The statement is wrong because ∠ABC+∠CAB+∠ACB=180
∘
.
But, ∠ABC=90
∘
given.
Therefore, ∠ACB+∠CAB=180
∘
−90
∘
=90
∘
.
So each of ∠ACB,∠CAB is less than 90
∘
.
Option C ⇒ The statement is true according to the reasoning for the statement in B option.
Option D ⇒ The statement is wrong because given triangle is a right angled triangle and Pythagoras theorem is always applicable to right triangles.

Answer:
(Hypotenuse)=10cm
Step-by-step explanation:
here base =8 cm and Height =6cm
then according to Pythagoras theorem
=>(Hypotenuse)²= (base)²+(height)²
=>(Hypotenuse)²=36+64
=>(Hypotenuse)²= 100
=>(Hypotenuse)=10cm
