Answer 1

$\huge\underline \mathfrak\orange{Answer}$

a) Exterior angle - The angle formed by a side with its extended adjacent side of a triangle is called an exterior angle of the triangle.

Exterior angle property states that the measure of exterior angles of a triangle is equal to the sum of its two interior opposite angles.

b) Altitude - Altitude of a triangle is the line segment passing through a vertex and perpendicular to the opposite side. The length of altitude is the shortest distance between the base and the vertex.

c) Median - To determine the median, the list of numbers should be arranged in order from lowest to highest. The number in the middle or the average of the two middle numbers is the median.

d) Hypotenuse - In a right triangle, hypotenuse is the side opposite to the right angle. It is the longest side of the triangle.

e) Isosceles triangle - Triangles which have two equal sides are called isosceles triangles.  

f) Orthocentre - The point where all the attitudes of the triangle (perpendicular from the vertices to the opposite side) meets is known as orthocentre.

g) Legs of a right triangle - The legs of a right triangle are the two sides that intersect to determine the right angle. The remaining side is called the hypotenuse.

h) Angle sum property of a triangle - Angle sum property of triangle states that the sum of interior angles of a triangle is 180°. Proof: Consider a ∆ABC, as shown in the figure below. Thus, the sum of the interior angles of a triangle is 180°.
