Here are four practice problems involving similar figures. 1) In the figure, KLMN is a square, and angle KJN = 45°.  Find the area of figure JKLMN. 2) In the diagram, HJLM is a square, and GH = 10.  Find the area of trapezoid GHJK. 3) In the diagram, BD = 5, CD = 10,…

1) The line shown passes through the point (A, 30).  Which of the following is closest to the value of A? (A) 58 (B) 59 (C) 60 (D) 61 (E) 62 2) Line A has a slope of and passes through the point (–2, 7).  What is the x-intercept of Line A? 3) Line J…

Here are eight practice problems involving circles.  The difficulty of these problems ranges from medium to very challenging. 1) In the diagram above, O is the center of the circle and angle AOB = 144º.  What is the area of the circle? Statement #1: The area of sector AOB is 40% of the area of…

  Hello! 🙂 This week, I’m solving a tough challenge question that you might have seen on our blog if you visit often! This challenge question draws on a whole host of geometry concepts and formulas, so it’s a great test for how much of geometry you really know. And just in case the board…

Earlier, we featured a blog of Coordinate Geometry practice questions.  Here are eight more questions, some of which are challenging. 1) Graph G has a line of symmetry of x = –5/2.  Graph G passes through the point (3, 3).  What is the x-coordinate of another point that must have a y-coordinate of 3? (A)…
