What is the midsegment formula?
Median of a trapezoid is a line segment found on the midpoint of the legs of a trapezoid. It is also known as mid-line or mid-segment. Its basic formula is AB + CD divided by 2.
The slope of line ab is 3 what is the slope of line CD if CD is parallel to ab?

How do you represent square root 13 on number line?
Draw a number line (l) and mark the points O, A, B and C such that OA = AB = BC = 1Draw CD ⊥ l, such that CD = 1 units.Join OCIn right ΔOCD,OD2 = OC2 + CD2Taking O as centre and D as radius, draw an arc which cuts l in FNow, draw EF ⊥ l, such that EF = 1 unitsJoin OE'In right ΔOEF,OE2 = OF2 + EF2Taking O as centre and OE as radius, draw an arc which cuts l in HNow, draw GH ⊥ l, such that GH = 1 unitsJoin OGIn right ΔOGH,Taking O as centre and OG as radius, draw an arc which cuts l in J.Now, draw IJ ⊥ l, such that IJ = 1 unitsJoin OI,In right ΔOIJ,Taking O as centre and OI as radius, draw an arc which cuts l in L.The point L represents on the number line.
How do you draw a parallelogram and label the vertices so AB and CD?

Explain why Ab and Ba are the same line but Cd and Dc are not not the same ray?
Ab and Ba are the same line because there are no endpoints to a line. Therefore, you can reverse the order of the letters. So, Cd and Dc are not the same ray because the first letter is the endpoint. So on ray Cd, point C is the endpoint and d is a point on the line coming from the endpoint. On ray Dc, D is the endpoint.
