Can someone please help me "Inscribed circles to triangles"? I watched a video, but it still doesn't make sense..... The video skips a lot of the steps and I'm not sure why...... Please help me!

Best ResponseYou've already chosen the best response.0Not bisectors, but yes, you'll need perpendiculars.

Best ResponseYou've already chosen the best response.0If you want to make the circle, then you need the intersection of angle bisectors.

Best ResponseYou've already chosen the best response.0One: Construct a circle and a tangent to the circle using a compass and straightedge. (4 points) Draw three random points on your paper. Construct the circle through these three points. Determine the circle's center. Construct a tangent to the circle, using one of the original three points as the point of tangency.

Best ResponseYou've already chosen the best response.0Oh, you're doing the reverse. You're starting with the circle, then circumscribing a triangle around it.

Best ResponseYou've already chosen the best response.0Two: Construct a circumscribed circle about a regular polygon using a compass and straightedge. (4 points) Choose a regular polygon from which you will draw a circumscribed circle. triangle  square  pentagon  hexagon Construct the circumscribed circle.

Best ResponseYou've already chosen the best response.0how is the circle made?

anonymous

Best ResponseYou've already chosen the best response.0"Circumscribed circle" means the circle is on the outside of the polygon.

anonymous

Best ResponseYou've already chosen the best response.0It says a circle inside any of those polygons. I chose a square.

Best ResponseYou've already chosen the best response.0Three: Construct an inscribed circle within a regular polygon using a compass and straightedge. (4 points) Choose a regular polygon from which you will draw an inscribed circle. Note: The polygon you choose must be different from the polygon you chose in problem 2. triangle  square  pentagon  hexagon Construct the inscribed circle.

phi

Best ResponseYou've already chosen the best response.1I would pick a square, and follow the same instructions as for the triangle. Bisect 2 angles and find the intersection to get the center of the circle. draw a perpendicular from the center to 1 side of the square to find the radius

Best ResponseYou've already chosen the best response.0Okay, how about Six: Explain, using complete sentences, how you can determine whether or not a circle may circumscribe a quadrilateral.

phi

Best ResponseYou've already chosen the best response.1Here is the professional answer: A quadrilateral is cyclic (i.e. may be inscribed in a circle) if one side subtends congruent angles at the two opposite vertices.

phi

Best ResponseYou've already chosen the best response.1How about opposite angles of a cyclic quadrilateral are supplementary (sum to 180º)

Best ResponseYou've already chosen the best response.0okay that makes much more sense lol thanks! Seven: Explain, using complete sentences, why an inscribed circle will only work within a regular polygon.

Best ResponseYou've already chosen the best response.0And, is there a video for this? Construct a circle and a tangent to the circle using a compass and straightedge. (4 points) Draw three random points on your paper. Construct the circle through these three points. Determine the circle's center. Construct a tangent to the circle, using one of the original three points as the point of tangency.

Best ResponseYou've already chosen the best response.1Construct a circle and a tangent to the circle using a compass and straightedge. draw the circle. draw a line from the center through the circle. mark the intersection. construct a perpendicular to the line through that point.

Best ResponseYou've already chosen the best response.1Determine the circle's center. I think you have to do this do construct the circle in the first place. Construct a tangent to the circle, using one of the original three points as the point of tangency. This is the same problem as the first one: Construct a circle and a tangent to the circle using a compass and straightedge.
