a) a rectangle, given perpendicular segment AB AND AC
b) a parallelogram, given two segment AB and AC with A, B, and C free points
c) a rhombus, given two segment AB and AC with AB ~ AC
d) a 30-60-90 triangle, given line segment AB as the hypotenuse of the triangle ]]> 2020-05-15 02:04:17 UTC https://padlet.com/reynalddy14/jnxrj7lftushbmda/wish/574096084 reynalddy14 https://padlet.com/reynalddy14/jnxrj7lftushbmda/wish/574100880 (a) Consider a set of 4 point consisting of 3 vertices of a triangle and the ortrocenter of that triangle. Prove that any one point of this set is the orthocenter of the triangle formed by the remaining three points. Such a set is called an orthocentric system. ]]> 2020-05-15 02:09:27 UTC https://padlet.com/reynalddy14/jnxrj7lftushbmda/wish/574100880 reynalddy14 https://padlet.com/reynalddy14/jnxrj7lftushbmda/wish/574112455 In section 1.3 a construction of an equilateral triangle starting from one side was given. This problem will expand upon those ideas.
a) draw a line segment and label its endpoint A and B. Construct a square having AB as one of its sides. Describe your construction and explain why it works
b) Draw another line segment and label it endpoints A and B. Construct a triangle ABC having a right angle at C so that the triangle remain right-angled no matter which vertex is dragged. Explain you construction and why it works. Is the effect of dragging the same at each vertex in your construction? If not why?]]> 2020-05-15 02:21:17 UTC https://padlet.com/reynalddy14/jnxrj7lftushbmda/wish/574112455 reynalddy14 https://padlet.com/reynalddy14/jnxrj7lftushbmda/wish/574118685 Using Sketchpad, in a new sketch place a point and label it N. Construct an equilateral triangle ABC such the N is the commong incenter, orthocenter, circumcenter and centroid of equilateral traingle ABC. Describe your construction and explain why it works]]> 2020-05-15 02:28:07 UTC https://padlet.com/reynalddy14/jnxrj7lftushbmda/wish/574118685 reynalddy14 https://padlet.com/reynalddy14/jnxrj7lftushbmda/wish/574129441 a) given a line segment AB and a point C above AB construct the point D on AB so that CD is perendicular to AB. We call D the foot of the perpendicular from C to AB. Prove that your construction works. ]]> 2020-05-15 02:40:10 UTC https://padlet.com/reynalddy14/jnxrj7lftushbmda/wish/574129441 reynalddy14 https://padlet.com/reynalddy14/jnxrj7lftushbmda/wish/574134936 a) Using Sketchpad draw two point and label the O and A. Construct a regular octagon having O as center and A as one vertex. In other words, construct an octagon by center and point.
b) Open a new sketch and draw aline segment CD (don't make it too long). Construct a regular octagon having CD as one side. In other words, construct an octagon by edge.]]> 2020-05-15 02:46:47 UTC https://padlet.com/reynalddy14/jnxrj7lftushbmda/wish/574134936
