Part A
Draw a line through point B that is perpendicular to line AC. Label the intersection of the line and AC as point D. Take a screenshot of your work, save it, and insert the image in the space below. (I added the photo)
Part B
Based on your construction, what do you know about ÎABD and ÎBCD? (I wrote that they were both right triangles, but it would be great if I had some conformation.
Part C
In terms of the trigonometric ratios for ÎABD, what is the length of BD? Insert text on the triangle in the GeoGebra geometry tool to show the length of BD. Take a screenshot of the triangle with the text, save it, and insert the image in the space below.
Part D
Using the formula for the area of a triangle, area = 1/2 x base x height, write an expression for the area of ÎABC. Base your answer on the work you did in parts A through C. Show your work. (I have no idea what to do here.)
Part E
In terms of the trigonometric ratios for ÎBCD, what is the length of BD? Insert text on the triangle in GeoGebra to show the length of BD. Take a screenshot of the triangle with the text, save it, and insert the image in the space below. (Same photo I added for Part C.)
Part F
Using the formula for the area of a triangle, area = 1/2 x base x height, write an expression for the area of ÎABC. This time, base your answer on the work you did in part E. Show your work. (Don't know what to do here.)
Part G
Next, create a line through point C that is perpendicular to AB. Label the intersection between the perpendicular line and AB as point E. Take a screenshot of the triangle with CE, save it, and insert the image in the space below. (Didn't do this.)
Part H
Based on your construction, what do you know about ÎACE and ÎBCE? (Didn't do this.)
Part I
In terms of the trigonometric ratios for ÎBCE, what is the length of CE? Insert text on the triangle in GeoGebra to show the length of CE. Take a screenshot of the triangle with the text, save it, and insert the image in the space below. (Didn't do this.)
Part J
Using the formula for the area of a triangle, area = 1/2 x base x height, write an expression for the area of ÎABC. Base your answer on the work you did in parts G through I. Show your work. (Didn't do this.)
Part K
Summarize the three formulas that you derived for the area of acute triangle âABC. Also describe the formulas in word form, using your own words.
Help quick please!!
