Answer:
Δ ABC is right angled
Step-by-step explanation:
If the triangle is right then the longest side squared will equal the sum of the squares on the other 2 sides.
longest side = 65, then
65² = 4225
16² + 63² = 256 + 3969 = 4225
Since 65² = 16² + 63² then Δ ABC is right
Answer:
We can know if it is a right angled triangle by using the Pythagoras theorem ( a²+b²=c²)
Step-by-step explanation:
To identify, we can take the largest length of the triangle as hypotanuse( that is, AC:65) And the rest as base and perpendicular ( 63 and 16 cm)
By applying Pythagoras theorem,
AB²+BC²= AC² ; (63)²+(16)²= (65)²
63² is 3969, 16² is 256… 65² is 4225.
Now, if 63²+16²:65²… then the triangle mentioned is a right angled triangle.
3969+256=4225
LHS = RHS, So, triangle ABC is a right angled triangle as it satisfies the condition of Pythagoras theorem.
