Measure Plot

angleat

Used in Symbolic view. Given the three points of an angle and

a fourth point as a location, displays the measure of the angle

defined by the first three points. The measure is displayed,

with a label, at the location in the Plot view given by the fourth

point. The first point is the vertex of the angle.

angleat(point1, point2, point3, point4)

Example:

In degree mode, angleat(point(0, 0), point(2√3,

0), point(2√3, 3), point(-6, 6)) displays

“appoint(0,0)=30.0” at point (–6,6)

angleatraw

Works the same as angleat, but without the label.

areaat

Used in Symbolic view. Displays the algebraic area of a

polygon or circle. The measure is displayed, with a label, at

the given point in Plot view.

areaat(polygon, point) or areaat(circle,

point)

Example:

areaat(circle(x^2+y^2=1), point(-4,4))

displays “acircle(x^2+y^2=1)= π” at point (-4, 4))

areaatraw

Works the same as areaat, but without the label.

distanceat

Used in Symbolic view. Displays the distance between 2

geometrical objects. The measure is displayed, with a label,

at the given point in Plot view.

distanceat(object1, object2, point)

Example:

distanceat(1+i, 3+3*i, 4+4*i) returns “1+i

3+3*i=2√2”

at point (4,4)
