Which of the following triangles will have its altitude outside the triangle? A) Acute Angled Triangle B) Right Angled Triangle C) Obtuse Angled Triangle D) Scalene Triangle
Answers
Answer:
Obtuse angle
Step-by-step explanation:
The perpendicular line joining the vertex to the opposite side is called an altitude
it is inside in acute , equilateral,Scalene, Isosceles triangles
It is outside in Obtuse triangle
It is a perpendicular vertex in Right triangle
Answer:
Option (C) is correct.
Step-by-step explanation:
(A) Acute angled triangle
An angle greater than 0° and less than 90° is called an acute angle triangle.
Its all the three altitudes lie inside the triangle.
Thus, option (A) is incorrect.
(B) Right angled triangle
In right triangle, there in only one altitude which lie inside the triangle.
Thus, option (B) is incorrect.
(C) Obtuse angled triangle
In obtuse triangle, two of its altitudes lie outside the triangle.
And one altitude lie inside the triangle.
Thus, option (C) is correct.
(D) Scalene triangle
It is a type of triangle in which all the three sides and angles are different lengths and measures respectively.
Its all the three altitudes lie inside the triangle.
Thus, option (D) is incorrect.
