If we reverse the angles and the sides, we know that's also a congruence postulate. We have to make sure that we have the corresponding vertices map up together. And what I want to do in this video is figure out which of these triangles are congruent to which other of these triangles. So let's see our congruent triangles. Problem 3 : Check whether two triangles are congruent or not. That's all the information we can have from the given figure. It has to be 40, 60, and 7, and it has to be in the same order.

That's the vertex of the 60-degree angle. Some of the worksheets displayed are 4 s sas asa and aas congruence, Examview, Triangle congruence quiz, Geometry, State if the two triangles are if they are, Unit 3 syllabus congruent triangles, Congruent triangles work 1, 5 congruent triangles. If these two guys add up to 100, then this is going to be the 80-degree angle. Since the information given in the figure is insufficient, we can not conclude whether the two triangles are congruent or not. Problem 13 : Check whether two triangles are congruent or not. So if you flip this guy over, you will get this one over here.

Since the information given in the figure is insufficient, we can not conclude whether the two triangles are congruent or not. And I want to really stress this, that we have to make sure we get the order of these right because then we're referring to-- we're not showing the corresponding vertices in each triangle. You might say, wait, here are the 40 degrees on the bottom. That's all the information we can have from the given figure. So over here, the 80-degree angle is going to be M, the one that we don't have any label for.

And then finally, you have your 40-degree angle here, which is your 40-degree angle here. Time permitting, I also ask one student from each team to write a team answer on the white board. It's on the 40-degree angle over here. So this is looking pretty good. We look at this one right over here.

And now let's look at these two characters. This problem reviews the strategy of proving triangles congruent to analyze or prove the properties of a figure. I ask them to make an effort, answer every problem and make educated guesses where they do not know the answers. So once again, these two characters are congruent to each other. So I'm going to go to N.

You don't have the same corresponding angles. They have to add up to 180. So it wouldn't be that one. So let's see if any of these other triangles have this kind of 40, 60 degrees, and then the 7 right over here. Once you find your worksheet, click on pop-out icon or print icon to worksheet to print or download.

So maybe these are congruent, but we'll check back on that. That's all the information we can have from the given figure.

Or another way to think about it, we're given an angle, an angle and a side-- 40 degrees, then 60 degrees, then 7. So we did this one, this one right over here, is congruent to this one right over there.

There might have been other congruent pairs. Problem 9 : Check whether two triangles are congruent or not. Since the information given in the figure is insufficient, we can not conclude whether the two triangles are congruent or not. And then we went from D to E. For this reason, I assign homework that reviews the types of multiple choice questions and free-response problems students will see on the quiz.

Following the lesson opener, I display the learning goals and agenda for the lesson using the overhead projector and review them briefly with the class. Here it's 60, 40, 7. That's all the information we can have from the given figure. Since the information given in the figure is insufficient, we can not conclude whether the two triangles are congruent or not. Here, the 60-degree side has length 7.
