27 Directed line segment PT has endpoints whose coordinates are P( 2,1) and T(4,7). Determine the coordinates of point J that divides the segment in the ratio 2 to 1. [The use of the set of axes below is optional.] Score 1: The student located point J graphically, but did not state its coordinates. Geometry (Common Core) - Jan. '16 [18] y xso I have some example questions here from Khan Academy on arc measure and like always I encourage you to pause the video after you see each of these questions and try to solve them before I do so this first question says what is the arc measure in degrees of Arc AC on circle P below so this is point a that is Point C and when they're talking about arc AC since they only have two letters hereThe angle formed by the intersection of 2 tangents, 2 secants or 1 tangent and 1 secant outside the circle equals half the difference of the intercepted arcs!Therefore to find this angle (angle K in the examples below), all that you have to do is take the far intercepted arc and near the smaller intercepted arc and then divide that number by two!Diagram NOT accurately drawn xo In the diagram, A, B, C and D are points on the circumference of a circle, centre O.

Step 1: Draw a circle with the required radius with centre O. Step 2: Join centre of the circle O and any point P on the circle. OP is the radius of the circle. Step 3: Draw a line perpendicular to radius OP through point P. This line will be a tangent to the circle at P. Two tangents can be drawn to a circle from a point outside of the circle.1 Line n intersects lines l and m, forming the angles shown in the computations. diagram below.
