INTRODUCTION OF GEOMERTY

  Bisection is the division of something into two equal or congruent parts, usually by a line, which is then called a bisector

congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other

Complementary Angles

When two angles add to 90°, we say they "Complement" each other.

Supplementary Angles

When two angles add to 180°, we say they "Supplement" each other.

Transitive Property

Unafanisha: 

If  A= B and B=C

So A=C

Vertical Angles

Angle zinazo angaliana zina fanana

Median of Triangle

is line connect the vertex of angle and the mid point. in triangle so its make congruent at base

Split Segment BC, into two equal part.

Does-the-median-of-a-triangle-form-the-right-angle?

Median does not form righ angle. MORE

 Altitude of Triangles

is line like median but not split the base at two equal part

So C and D , are not center(midpoint) 

Its form right angle. AND perpendecular

BD Segment is perndicular to AC

 

Perpendicular Bisector

perpendicular means form 90 degree

Perpendicular Bisector means line pass to segment and form 90 degree and at the same time , form midpoint(cut segment to congruent part)

<ADC And <CDB  are form right angle 

D is mid point

Segment AB Is Altitude(bcoz of right angles) and also is a median(bocz of conguent)

VERTICAL ANGLES

MERIDIAN

A median of a triangle is a line segment that joins a vertex to the mid-point of the side that is opposite to that vertex. In the figure, AD is the median that divides BC into two equal halves, that is, DB = DC.

ALTITUDE

Form right angles

PERPENDICULAR BISECTOR

there is line which divide segment into two equal part , and form right angles

BISECTOR:

can bisect line  or angle
