How to find the midpoint of a line segment (Grade C) (Average of x coordinates Average of y coordinates)
Angles in a triangle Angles in a triangle = 180°
Angles on a straight line Angles on a straight line = 180°
Angles in a quadrilateral Angles in a quadrilateral = 360°
Angles around a point Angles around a point = 360°
Relationship between exterior angles and opposite angles of a triangle Exterior angle = sum of opposite interior angles
What is special about isosceles triangles They have two sides and angles the same
Name three types of angles on parallel lines that are equal Vertically Opposite, Alternate Corresponsing
Name the type of angles that = 180° on parallel lines Interior
What are parallelograms? Parallelograms are quadrilaterals made from two sets of parallel lines
In a parallelogram, opposite angles... ...are equal
In a parallelogram, neighboring angles... ...add up to 180°
What is a shape with 9 sides called? A nonagon
In a polygon (regular or irregular) the sum of the exterior angles =... 360°
In a polygon (regular or irregular) the sum of the interior angles =... (number of sides - 2) X 180°
In a REGULAR polygon, exterior angle =... 360° / Number of Sides
In a REGULAR polygon, interior angle =... 180° - Exterior Angle
Area of sector =... x / 360° X Area of full Circle
Length of arc =... x / 360° X Circumference of full Circle
How to find the area of a segment 3. Area of segment = Area of sector - area of triangle
Why are these bearings wrong: 3°, 55° 78°, 9° Because they need to be written to three figures (eg. 003°, 055°, 078°, 009°)
If two perpendicular lines have the gradients M1 & M2 then... M2 will be the reciprical of M1 M1 X M2 = -1
