The circle k intersects the line AC at points E and F. Prove that the lines FM, AD and BC meet at one point. You can also use it to find the area of a circle: A = π * R² = π * 14² = 615.752 cm². Note that the formula works whether P is inside or outside the circle. If less than radius , then its within the circle. Learner’s Material Module 4 7 This instructional material was collaboratively developed and reviewed by educators from public and private schools, colleges, and/or universities. Let's assume it's equal to 14 cm. 5. Let E be intersection of AB and CD and let F be intersection of AD and BC. If (xi - x)^2 + (yi - y)^2 is less than d^2, it's inside.

In the diagram below, AB, BC, and AC are tangents to circle O at points F, E, and D, respectively, 6, 5, and BE = 4. Since the three points of a circle are given, we can use the equation of a circle in general form to solve for D, E, and F. For (2, 3), if x = 2 and y = 3, the equation becomes. Solution: ∠BEC = ∠EDC + ∠ECD [Sum of interior opposite angles is equal to exterior angle] ⇒ 130° = ∠EDC + 20° ⇒ ∠EDC = 130° – 20° = 110° ⇒ ∠BDC = 110° Step 3 Find the midpoint between the orthocenter and circumcenter. 1 Join OP and construct the midpoint M of OP. In this situation, the circle is called an inscribed circle, and its center is called the inner center, or incenter. Set the compass width to the circle’s radius. We can eliminate answer choices B, C, and E.
