Answer 1

Answer:

a) exterior angle - the angle between a side of a rectilinear figure and an adjacent side extended outward.

b) altitude- altitude is a distance measurement, usually in the vertical or "up" direction, between a reference datum and a point or object.

c)Median-The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average

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

e) Isosceles triangle-isosceles triangle is a triangle that has two sides of equal length

f)Orthocentre-The orthocenter is the point where all the three altitudes of the triangle cut or intersect each other.

g)legs of a right triangle -The sides adjacent to the right angle are called legs

h)angle sum property of a triangle-Angle sum property of triangle states that the sum of interior angles of a triangle is 180

Answer 2

Answer:

(a) the angle between a side of a polygon and an extended adjacent side.

(b) the height of anything above a given planetary reference plane, especially above sea level on earth.

(c) The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average.

(d) a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle.

(e) an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.

(f) the point of intersection of the three altitudes of a triangle.

(g) A leg of a triangle is one of its sides. For a right triangle, the term "leg" generally refers to a side other than the one opposite the right angle (which is termed the hypotenuse). Legs are also known as catheti.

(h) Angle sum property of triangle states that the sum of interior angles of a triangle is 180°. Proof: ... Thus, the sum of the interior angles of a triangle is 180°.
